Fluid control devices and methods of using the same

ABSTRACT

An apparatus includes an inlet configured to be placed in fluid communication with a bodily fluid source and an outlet configured to be placed in fluid communication with a fluid collection device. A sequestration portion can be configured to receive an initial volume of bodily fluid. A flow controller disposed in the sequestration portion can be configured to transition from a first state to a second state in response to contact with the initial volume of bodily fluid. As the flow controller transitions, a negative pressure differential can be defined that is operable to draw the initial volume of bodily fluid into the sequestration portion. When the flow controller is in the second state, the negative pressure differential can be substantially equalized such that (1) the sequestration portion sequesters the initial volume and (2) a subsequent volume of bodily fluid can be transferred from the inlet to the outlet.

BACKGROUND

The invention relates generally to the procurement of bodily fluidsamples, from a bodily source or from a container of bodily fluids, andmore particularly to fluid diversion, sequestration, and/or isolationdevices and methods for procuring bodily fluid samples with reducedcontaminants such as dermally residing microbes and/or othercontaminants exterior to the bodily fluid source.

Health care practitioners routinely perform various types of microbialas well as other broad diagnostic tests on bodily samples obtained frompatients using either parenterally obtained bodily fluids or bodilyfluid collections stored in containers or reservoirs. As advanceddiagnostic technologies evolve and improve, the speed, accuracy (bothsensitivity and specificity), and value of information that can beprovided to clinicians continues to improve. Maintaining the integrityof the bodily fluid sample during and/or after collection ensures thatanalytical diagnostic results are representative of the in vivoconditions of a patient. Examples of diagnostic technologies that arereliant on high quality, non-contaminated, and/or unadulterated bodilyfluid samples include but are not limited to microbial detection,molecular diagnostics, genetic sequencing (e.g., deoxyribonucleic acid(DNA), ribonucleic acid (RNA), next-generation sequencing (NGS), etc.),biomarker identification, and the like. When biological matter, whichcan include cells external to the intended source for sampleprocurement, and/or other external contaminants are inadvertentlyincluded in the bodily fluid sample that is to be analyzed, there is anopportunity for inaccurate test results to be derived. In short, whenthe purity of the sample intended to be derived from a specific bodilyfluid source or from a container holding a collected bodily fluid iscompromised during the specimen procurement process or during theprocess of transferring a sample from a fluid collection, resultantanalytical test results may be inaccurate, distorted, adulterated,falsely positive, falsely negative, and/or otherwise not representativeof the actual, in vivo conditions of the patient, which in turn, caninform faulty, inaccurate, confused, unsure, low-confidence, and/orotherwise undesired clinical decision making.

In some instances, patient samples (e.g., bodily fluids) are tested forthe presence of one or more potentially undesirable microbes, such asbacteria, fungi, or yeast (e.g., Candida). In some instances, microbialtesting may include incubating patient samples in one or more sterileand/or non-sterile vessels that may contain culture media, commonadditives, and/or other types of solutions that are conducive tomicrobial growth. In other instances, the sample in the vessel may beanalyzed directly (i.e., not incubated) and may not contain culturemedia or additives associated with incubating the specimen. In stillother instances, various technologies can be employed to assist in thedetection of the presence of microbes as well as other types ofbiological matter, specific types of cells, biomarkers, proteins,antigens, enzymes, blood components, and/or the like during diagnostictesting. Examples include but are not limited to molecular polymerasechain reaction (PCR), magnetic resonance and other magnetic analyticalplatforms, automated microscopy, spatial clone isolation, flowcytometry, whole blood (“culture free”) specimen analysis (e.g., NGS)and associated technologies, morphokinetic cellular analysis, and/orother common or evolving and advanced technologies utilized in theclinical or research laboratory environment to characterize patientspecimens and/or to detect, identify, type, categorize, quantify, and/orcharacterize specific organisms, antibiotic susceptibilities, and/or thelike.

In some instances, the detection of the presence of microbes includesallowing the microbes, and/or organisms to grow for an amount of time(e.g., a variable amount of time from less than an hour to a few hoursto several days—which can be longer or shorter depending on thediagnostic technology employed). The microbe and/or organism growth canthen be detected by automated, continuous monitoring, and/or othermethods specific to the analytical platform and technology used fordetection, identification, and/or the like.

In culture testing, for example, when microbes are present in thepatient sample, the microbes flourish over time in the culture mediumand, in some instances, automated monitoring technologies can detectcarbon dioxide produced by organism growth. The presence of microbes inthe culture medium (as indicated by observation of carbon dioxide and/orvia other detection methods) suggests the presence of the same microbesin the patient sample which, in turn, suggests the presence of the samemicrobes in the bodily fluid of the patient from whom the sample wasobtained. Accordingly, when microbes are determined to be present in theculture medium (or more generally in the sample used for testing), thepatient may be diagnosed and prescribed one or more antibiotics or othertreatments specifically designed to treat or otherwise remove theundesired microbes from the patient.

Patient samples, however, can become contaminated during procurementand/or otherwise can be susceptible to false positive or false negativeresults. For example, microbes from a bodily surface (e.g., dermallyresiding microbes) that are dislodged during the specimen procurementprocess (which can include needle insertion into a patient, specimenprocurement via a lumen-containing device such as a peripheral IVcatheter (PW), a central line (PICC) and/or other indwellingcatheter(s), collection with a syringe or any other suitable meansemployed to collect a patient specimen), either directly or indirectlyvia tissue fragments, hair follicles, sweat glands, and other skinadnexal structures, can be subsequently transferred to a culture medium,test vial, or other suitable specimen collection or transfer vessel withthe patient sample and/or included in the specimen that is to beanalyzed for non-culture based testing. Another possible source ofcontamination is from the person drawing the patient sample (e.g., adoctor, phlebotomist, nurse, technician, etc.). Specifically, equipment,supplies, and/or devices used during a patient sample procurementprocess often include multiple fluidic interfaces (by way of example,but not limited to, patient to needle, needle to transfer adapter,transfer adapter to sample vessel, catheter hub to syringe, syringe totransfer adapter, needle/tubing to sample vessels, and/or any otherfluidic interface or any combination thereof) that can each introducepoints of potential contamination. In some instances, such contaminantsmay thrive in a culture medium and/or may be identified by anothernon-culture based diagnostic technology and eventually may yield a falsepositive and/or a false negative microbial test result, which mayinaccurately reflect the presence or lack of such microbes within thepatient (i.e., in vivo).

Such inaccurate results because of contamination and/or other sources ofadulteration that compromise the purity of the sample are a concern whenattempting to diagnose or treat a wide range of suspected illnesses,diseases, infections, patient conditions or other maladies of concern.For example, false negative results from microbial tests may result in amisdiagnosis and/or delayed treatment of a patient illness, which, insome cases, could result in the death of the patient. Conversely, falsepositive results from microbial tests may result in the patient beingunnecessarily subjected to one or more anti-microbial therapies, whichmay cause serious side effects to the patient including, for example,death, as well as produce an unnecessary burden and expense to thehealth care system due to extended length of patient stay and/or othercomplications associated with erroneous treatments. The use ofdiagnostic imaging equipment attributable to these false positiveresults is also a concern from both a cost as well as patient safetyperspective as unnecessary exposure to concentrated radiation associatedwith a variety of imaging procedures (e.g., CT scans) has many knownadverse impacts on long-term patient health.

In some instances, devices and/or systems can be used to reduce thelikelihood of contamination, adulteration, and/or the like of bodilyfluid samples for testing. For example, some known devices can beconfigured to collect, divert, separate, and/or isolate or sequester aninitial volume of bodily fluid that may be more likely to containcontaminants such as dermally residing microbes or the like. Some suchdevices, however, can be cumbersome, non-intuitive, perceived asdifficult to use, inappropriate or unusable as intended for the targetpatient population, etc. In addition, some such devices can requiretraining, user observation, intervention by more than one user, and/orcan otherwise present challenges that can lead to limited efficacy basedon variables including environmental, educational, clinician skill,patient condition, and/or the like. In some instances, such challengescan complicate the collection of consistently high quality samples thatare non-contaminated, sterile, unadulterated, etc., which in turn, canimpact the validity of test result outcomes.

As such, a need exists for fluid diversion devices and methods forprocuring bodily fluid samples with reduced contaminants such asdermally residing microbes and/or other contaminants exterior to thebodily fluid source. Furthermore, a need exists for such devices thatare user-friendly, utilize little to no user-intervention and/oractuation, demonstrate consistent efficacy, and/or address challengesassociated with collecting bodily fluid samples.

DETAILED DESCRIPTION

Any of the fluid control devices described herein can be configured toreceive, procure, and/or transfer a flow, bolus, volume, etc., of bodilyfluid. A first reservoir, channel, flow path, or portion of the devicecan receive an initial amount of the bodily fluid flow, which then canbe substantially or fully sequestered (e.g., contained or retained,circumvented, isolated, segregated, vapor-locked, separated, and/or thelike) in or by the first reservoir or first portion of the device. Insome instances, contaminants such as dermally residing microbes or thelike can be included and/or entrained in the initial amount of thebodily fluid and likewise are sequestered in or by the first reservoiror first portion of the device. Once the initial amount is sequestered,any subsequent amount of the bodily fluid flow can be diverted,channeled, directed, flow controlled (e.g., manually, automatically,and/or semi-automatically) to a second reservoir, second portion of thedevice, and/or any additional flow path(s). Thus, with the initialamount sequestered, any additional and/or subsequent amount(s) of bodilyfluid are substantially free from contaminants that may otherwiseproduce inaccurate, distorted, adulterated, falsely positive, falselynegative, etc., results in some diagnostics and/or testing. In someinstances, the initial amount of bodily fluid also can be used, forexample, in other testing such as those less affected by the presence ofcontaminants. In other instances, the initial amount of bodily fluid canbe discarded as a waste volume, can be infused back into the patient,and/or can be used for any other suitable clinical application.

In some embodiments, a fluid control device includes an inlet and anoutlet. The inlet is configured to be placed in fluid communication witha bodily fluid source or an intermediary bodily fluid transfer deviceand the outlet is configured to be placed in fluid communication with afluid collection device (e.g., a sample bottle, container, reservoir,syringe, evacuated container, dish, vial, lumen-containing device,and/or any other suitable bodily fluid collection and/or transferdevice). The fluid control device includes a sequestration portionconfigured to be in fluid communication with the inlet and configured toreceive an initial volume of bodily fluid from the bodily fluid source.In some embodiments, the fluid control device can include a flowcontroller disposed in the sequestration portion of the fluid controldevice. The flow controller is configured to transition between a firststate and a second state in response to contact with a portion of theinitial volume of bodily fluid. The fluid control device can beconfigured such that a negative pressure differential is defined betweenthe sequestration portion and the inlet as the flow controllertransitions from the first state to the second state that is operable todraw the initial volume of bodily fluid from the inlet into thesequestration portion. The fluid control device can be configured suchthat the negative pressure differential is substantially equalized whenthe flow controller is in the second state such that (1) thesequestration portion sequesters the initial volume of bodily fluid and(2) a subsequent volume of bodily fluid can be transferred from theinlet to the outlet.

In some embodiments, an apparatus includes an inlet configured to beplaced in fluid communication with a bodily fluid source and an outletconfigured to be placed in fluid communication with a fluid collectiondevice. A sequestration portion can be in fluid communication with theinlet and configured to receive an initial volume of bodily fluid fromthe inlet. The sequestration portion can include a selectively permeablevent configured to at least temporarily vent the sequestration portionto initiate a flow of the initial volume of bodily fluid from the bodilyfluid source, through the inlet, and into the sequestration portion. Aflow controller can be disposed in the sequestration portion andconfigured to transition from a first state to a second state inresponse to contact with a portion of the initial volume of bodilyfluid. The transitioning of the flow controller can be configured toproduce a negative pressure differential between the sequestrationportion and the inlet such that the sequestration portion receives theinitial volume of bodily fluid. When the flow controller is in thesecond state, the negative pressure differential can be substantiallyequalized such that (1) the sequestration portion sequesters the initialvolume of bodily fluid and (2) a subsequent volume of bodily fluid canbe transferred from the inlet to the outlet.

In some embodiments, a method of using a flow control device to obtain abodily fluid sample with reduced contamination can include establishingfluid communication between a bodily fluid source and an inlet of theflow control device. A sequestration portion of the flow control devicecan be vented to produce a first negative pressure differential betweenthe sequestration portion and the inlet. The sequestration portion canreceive a portion of an initial volume of bodily fluid from the inlet inresponse to the first negative pressure differential. A flow controllercan be disposed in the sequestration portion and can transition from afirst state to a second state in response to the flow controller beingplaced in contact with the portion of the initial volume of bodilyfluid. The transitioning of the flow controller can be configured toproduce a second negative pressure differential between thesequestration portion and the inlet such that the sequestration portionreceives the initial volume of bodily fluid from the inlet. The initialvolume of bodily fluid can be sequestered in the sequestration portionwhen the flow controller is placed in the second state, and a subsequentvolume of bodily fluid can be transferred from the inlet to an outlet influid communication with a fluid collection device.

In some embodiments, a fluid control device includes an inlet and anoutlet. The inlet is configured to be placed in fluid communication witha bodily fluid source or an intermediary bodily fluid transfer deviceand the outlet is configured to be placed in fluid communication with afluid collection device (e.g., a sample bottle, container, reservoir,syringe, evacuated container, dish, vial, lumen-containing device,and/or any other suitable bodily fluid collection and/or transferdevice). In some embodiments, the fluid control device has a first statein which an initial volume of bodily fluid can flow from the inlet to asequestration and/or diversion portion of the fluid control device(which can be formed by or in the fluid control device or coupledthereto) and a second state in which (1) the initial volume issequestered in the sequestration and/or diversion portion of the fluidcontrol device, and (2) a subsequent volume of bodily fluid, beingsubstantially free of contaminants, can flow from the bodily fluidsource, through at least a portion of the fluid control device, and intothe fluid collection device. The fluid control device is configured totransition from the first state to the second state after thesequestration and/or diversion portion receives the initial volume.

In some embodiments, a fluid collection device can include, can define,and/or can be actuated to generate a negative pressure condition insidethe fluid collection device, which in turn, can facilitate withdrawal ofbodily fluid from the bodily fluid source (e.g., the patient) into thefluid collection device via a vacuum or suction force. In embodiments inwhich the fluid collection device is an evacuated container or the like,the container can include a vacuum seal or the like that can betransitioned from a sealed state to an unsealed state. In someinstances, a user can couple an evacuated container to an outlet of afluid control device such as those described herein after an initialportion of the bodily fluid is diverted and/or sequestered, which inturn, can limit and/or substantially prevent an initial portion of thebodily fluid (potentially containing contaminants) from beingtransferred into the container (e.g., fluid collection device).

In some embodiments, a fluid control device includes an inlet device anda diverter. The inlet device is configured to be placed in fluidcommunication with a bodily fluid source. The diverter includes an inletconfigured to fluidically couple the diverter to the inlet device and anoutlet configured to fluidically couple the diverter to a samplereservoir. The diverter defines a sequestration chamber (or portion).The diverter has a first state in which an initial volume of bodilyfluid can flow from the inlet device to the sequestration chamber and asecond state in which (1) the sequestration chamber sequesters theinitial volume, and (2) a subsequent volume of bodily fluid, beingsubstantially free of contaminants, can flow through the inlet deviceand the diverter, out the outlet of the diverter, and into the samplereservoir. In some embodiments, the diverter is configured toautomatically transition from the first state to the second state afterthe sequestration chamber receives the initial volume while in otherembodiments, the transition can be achieved manually or via any suitablemeans.

As used in this specification and the claims, the singular forms “a,”“an” and “the” include plural referents unless the context clearlydictates otherwise. Thus, for example, the term “a member” is intendedto mean a single member or a combination of members, “a material” isintended to mean one or more materials, or a combination thereof.

As used herein, the terms “about,” “approximate,” and/or “substantially”when used in connection with a stated value and/or geometricrelationships is intended to convey that the structure so defined isnominally the value stated and/or the geometric relationship described.In some instances, the terms “about,” “approximately,” and/or“substantially” can generally mean and/or can generally contemplate plusor minus 10% of the value or relationship stated. For example, about0.01 would include 0.009 and 0.011, about 0.5 would include 0.45 and0.55, about 10 would include 9 to 11, and about 1000 would include 900to 1100. While a value stated may be desirable, it should be understoodthat some variance may occur as a result of, for example, manufacturingtolerances or other practical considerations (such as, for example, thepressure or force applied through a portion of a device, conduit, lumen,etc.). Accordingly, the terms “about,” “approximately,” and/or“substantially” can be used herein to account for such tolerances and/orconsiderations. Similarly, in some instances, when comparing like orsimilar components, features, characteristics, etc., the term“substantially” can be used herein to account for tolerances and/orother practical considerations. For example, a pressure differentialbetween two components can be said to be “substantially” equalized whenthe pressures thereof are nominally equal or the same within a practicalor functional tolerance.

As used herein, “bodily fluid” can include any fluid, tissue orbiological material (e.g., as a constituent of the fluid or apart fromthe fluid) obtained directly from a body of a patient or indirectly froma patient (e.g., via an intermediate collection device, a container, abiopsy needle, a scalpel, and/or the like). For example, “bodily fluid”can include, but is not limited to, blood (e.g., whole blood orcomponents of blood such as platelets or other components thereof),cerebrospinal fluid, urine, bile, lymph, saliva, synovial fluid, serousfluid, pleural fluid, amniotic fluid, mucus, sputum, vitreous, air,and/or the like, any type of tissue (e.g., tumor, organ, muscle,tendon), and/or any combination thereof.

As used herein, the words “proximal” and “distal” refer to the directioncloser to and away from, respectively, a user who would place the deviceinto contact with a patient. Thus, for example, the end of a devicefirst touching the body of the patient would be the distal end, whilethe opposite end of the device (e.g., the end of the device beingmanipulated by the user) would be the proximal end of the device.

As described in further detail herein, any of the devices and methodscan be used to procure bodily fluid samples with reduced contaminationby, for example, diverting a “pre-sample” volume of bodily fluid priorto collecting a “sample” volume of bodily fluid. Each of the terms“pre-sample,” “first,” and/or “initial,” can be used interchangeably todescribe and/or refer to an amount, portion, or volume of bodily fluidthat is transferred, diverted, and/or sequestered prior to procuring the“sample” volume. In some embodiments, the terms “pre-sample,” “first,”and/or “initial” can refer to a predetermined, defined, desired, orgiven volume, portion, or amount of bodily fluid. For example, in someembodiments, a predetermined and/or desired pre-sample volume of bodilyfluid can be about 0.01 milliliter (mL), about 0.1 mL, about 0.2 mL,about 0.3 mL, about 0.4 mL, about 0.5 mL, about 1.0 mL, about 2.0 mL,about 3.0 mL, about 4.0 mL, about 5.0 mL, about 10.0 mL, about 20 mL,about 50 mL, and/or any volume or fraction of a volume therebetween. Inother embodiments, the pre-sample volume can be greater than 50 mL orless than 0.1 mL. In some specific embodiments, a predetermined and/ordesired pre-sample volume can be between about 0.1 mL and about 5.0 mL.In other embodiments, the pre-sample volume can be, for example, a dropof bodily fluid, a few drops of bodily fluid, a combined volume of anynumber of lumen that form, for example, a flow path (or portion thereof)from the bodily fluid source to an initial collection chamber, portion,reservoir, etc. (e.g., a sequestration chamber).

On the other hand, the terms “sample,” “second,” and/or “subsequent”when used in the context of a volume of bodily fluid can refer to avolume, portion, or amount of bodily fluid that is either a randomvolume or a predetermined or desired volume of bodily fluid collectedafter transferring, diverting, sequestering, and/or isolating thepre-sample volume of bodily fluid. For example, in some embodiments, adesired sample volume of bodily fluid can be about 10 mL to about 60 mL.In other embodiments, a desired sample volume of bodily fluid can beless than 10 mL or greater than 60 mL. In some embodiments, for example,a sample volume can be at least partially based on one or more tests,assays, analyses, and/or processes to be performed on the sample volume.

The embodiments described herein can be configured to selectivelytransfer bodily fluid to one or more fluid collection device(s). In someembodiments, a fluid collection device can include, but is not limitedto, any suitable vessel, container, reservoir, bottle, adapter, dish,vial, syringe, device, diagnostic and/or testing machine, and/or thelike. By way of specific example, in some instances, any of theembodiments and/or methods described herein can be used to transfer asample volume into a fluid collection device such as any of thosedescribed in detail in U.S. Pat. No. 8,197,420 entitled, “Systems andMethods for Parenterally Procuring Bodily-Fluid Samples with ReducedContamination,” filed Dec. 13, 2007 (“the ‘420 Patent”), the disclosureof which is incorporated herein by reference in its entirety.

Any of the sample containers, reservoirs, bottles, dishes, vials, etc.,described herein can be devoid of contents prior to receiving a samplevolume of bodily fluid or can include, for example, any suitableadditive, culture medium, and/or the like. For example, in someembodiments, a sample reservoir can include, for example, any suitableadditive and/or the like. An additive can be any suitable substance,enzyme, oil, fluid, compound, chemical, etc., which occupies at least aportion of the inner volume defined by the sample reservoir. Specificexamples can include but are not limited to heparin, citrate, acidcitrate dextrose (ACD), ethylenediaminetetraacetic acid (EDTA), oxalate,sodium polyanethol sulfonate (SPS), and/or the like. In otherembodiments, a sample reservoir can contain, for example, an aerobicculture medium or an anaerobic culture medium. In general, a culturemedium is a nutrient rich and/or environmentally controlled medium thatpromotes growth (and/or any other suitable media), which occupies atleast a portion of the inner volume defined by the sample reservoir. Inuse, a sample reservoir (e.g., culture bottle) can receive a bodilyfluid sample, which can then be tested (e.g., via in vitro diagnostic(IVD) tests and/or any other suitable test) for the presence of, forexample, Gram-Positive bacteria, Gram-Negative bacteria, yeast, fungi,and/or any other organism. If testing of the culture medium yields apositive result, the culture medium can be subsequently tested usingvarious methods (e.g., a PCR-based system) to identify a specificorganism. As described in further detail herein, in some instances,diverting a pre-sample or initial volume of bodily fluid can reduceand/or substantially eliminate contaminants in the bodily fluid samplethat may otherwise lead to inaccurate test results.

While the term “culture medium” can be used to describe a substanceconfigured to react with organisms in a bodily fluid (e.g.,microorganisms such as bacteria) and the term “additive” can be used todescribe a substance configured to react with portions of the bodilyfluid (e.g., constituent cells of blood, serum, synovial fluid, etc.),it should be understood that a sample reservoir can include any suitablesubstance, liquid, solid, powder, lyophilized compound, gas, etc.Moreover, when referring to an “additive” within a sample reservoir, itshould be understood that the additive could be and/or could include aculture medium (e.g., an aerobic or an anaerobic culture medium), anadditive and/or any other suitable substance, and/or any combination ofsubstances, media, etc. contained in the sample reservoir. That is tosay, the embodiments described herein can be used with any suitablesample reservoir and/or the like containing any suitable substance.Furthermore, any of the embodiments and/or methods described herein canbe used to transfer a volume of bodily fluid to a sample reservoirand/or the like that does not contain a culture medium, additive, and/orany other substance prior to receiving a flow of bodily fluid.

While some of the embodiments are described herein as being used forprocuring bodily fluid for one or more culture sample testing, it shouldbe understood that the embodiments are not limited to such a use. Any ofthe embodiments and/or methods described herein can be used to transfera flow of bodily fluid to any suitable device that is placed in fluidcommunication therewith. Thus, while specific examples are describedherein, the devices, methods, and/or concepts are not intended to belimited to such specific examples.

The embodiments described herein and/or portions thereof can be formedor constructed of one or more biocompatible materials. In someembodiments, the biocompatible materials can be selected based on one ormore properties of the constituent material such as, for example,stiffness, toughness, durometer, bioreactivity, etc. Examples ofsuitable biocompatible materials include metals, glasses, ceramics, orpolymers. Examples of suitable metals include pharmaceutical gradestainless steel, gold, titanium, nickel, iron, platinum, tin, chromium,copper, and/or alloys thereof. A polymer material may be biodegradableor non-biodegradable. Examples of suitable biodegradable polymersinclude polylactides, polyglycolides, polylactide-co-glycolides (PLGA),polyanhydrides, polyorthoesters, polyetheresters, polycaprolactones,polyesteramides, poly(butyric acid), poly(valeric acid), polyurethanes,and/or blends and copolymers thereof. Examples of non-biodegradablepolymers include nylons, polyesters, polycarbonates, polyacrylates,polymers of ethylene-vinyl acetates and other acyl substituted celluloseacetates, non-degradable polyurethanes, polystyrenes, polyvinylchloride, polyvinyl fluoride, poly(vinyl imidazole), chlorosulphonatepolyolefins, polyethylene oxide, and/or blends and copolymers thereof.

The embodiments described herein and/or portions thereof can includecomponents formed of one or more parts, features, structures, etc. Whenreferring to such components it should be understood that the componentscan be formed by a singular part having any number of sections, regions,portions, and/or characteristics, or can be formed by multiple parts orfeatures. For example, when referring to a structure such as a wall orchamber, the structure can be considered as a single structure withmultiple portions, or multiple, distinct substructures or the likecoupled to form the structure. Thus, a monolithically constructedstructure can include, for example, a set of substructures. Such a setof substructures may include multiple portions that are eithercontinuous or discontinuous from each other. A set of substructures canalso be fabricated from multiple items or components that are producedseparately and are later joined together (e.g., via a weld, an adhesive,or any suitable method).

Referring now to the drawings, FIG. 1 is a schematic illustration of afluid control device 100 according to an embodiment. Generally, thefluid control device 100 (also referred to herein as “control device” or“device”) is configured to withdraw bodily fluid from a patient. A firstportion or amount (e.g., an initial amount) of the withdrawn bodilyfluid is sequestered from a second portion or amount (e.g., a subsequentamount) of the withdrawn bodily fluid. In this manner, contaminants orthe like can be sequestered within the first portion or amount, leavingthe second portion or amount substantially free of contaminants. Thesecond portion or amount of bodily fluid can then be used as abiological sample in one or more tests for the purpose of medicaldiagnosis and/or treatment (e.g., a blood culture test or the like), asdescribed in more detail herein. The first portion or amount of bodilyfluid can be discarded as waste or can be used in any suitable test(e.g., testing that is less likely to produce false, inaccurate,distorted, inconsistent, and unreliable results as a result of potentialcontaminants contained therein). In other instances, the first portionor amount of bodily fluid can be infused back into the patient and/orused for any other suitable purpose. .

The control device 100 can be any suitable shape, size, and/orconfiguration. For example, in some embodiments, the control device 100can have a size that is at least partially based on a volume of bodilyfluid at least temporarily stored, for example, in a sequestration,diversion, isolation, and/or storage portion of the control device 100.As described in further detail herein, the control device 100 can beconfigured to transition between operating modes such that (1) the firstportion or amount of bodily fluid selectively flows through at least afirst portion of the fluid control device and is subsequentlysequestered therein, and (2) the second portion of amount of bodilyfluid selectively flows through at least a second portion of the fluidcontrol device and into a fluid collection device or the like. In someembodiments, the control device 100 can be configured to transitionbetween operating modes automatically (e.g., based on pressuredifferential, time, electronic signal or instruction, saturation of amembrane or member, an absorbent and/or barrier material, etc.) or viaand/or in response to intervention (e.g., user intervention, mechanicalintervention, or the like).

The control device 100 includes an inlet 132 at least one outlet 136,and a sequestration and/or diversion portion 134 (also referred toherein as “sequestration portion”). In addition, the control device 100defines one or more fluid flow paths 133 between the inlet 132 and thesequestration portion 134 and/or between the inlet 132 and the outlet(s)136.

The inlet 132 of the control device 100 is configured to be placed influid communication with a bodily fluid source. In some embodiments, theinlet 112 can be coupled to and/or can include an inlet device such as,for example, an intravenous (IV) catheter, a needle, a peripherallyinserted central catheter (PICC), a syringe, a port, a coupler, one ormore pieces of sterile tubing, and/or any other suitablelumen-containing device and/or intermediary transfer device. In someembodiments, the inlet can be a port, a valve, and/or the like such as,for example, a Luer Lok® or any other suitable coupler. In someembodiments, the inlet (e.g., port or coupler) can be configured tocouple to an access or inlet device in fluid communication with apatient (e.g., a placed or indwelling IV catheter or needle) or otherbodily fluid source. In some other embodiments, the inlet (e.g., port orcoupler) can be configured to couple to a corresponding port or couplerof a collection reservoir holding collected bodily fluid, for example.In some embodiments, the inlet 132 can be physically and fluidicallycoupled to the access or inlet device via a lock, coupler, port, etc. Inother embodiments, the inlet 132 can be in fluid communication with theaccess or inlet device via an intermediate lumen-containing device suchas, for example, sterile tubing or the like. In still other embodiments,the inlet 132 of the control device 100 can form and/or can beintegrally or monolithically formed with the access or inlet device.

The sequestration portion 134 of the control device 100 is at leasttemporarily placed in fluid communication with the inlet 132 via thefluid flow path(s) 133. As described in further detail herein, thesequestration portion 134 is configured to (1) receive a flow and/orvolume of bodily fluid from the inlet 110 and (2) sequester (e.g.,separate, divert, segregate, contain, retain, isolate, etc.) the flowand/or volume of bodily fluid therein.

The sequestration portion 134 can be any suitable shape, size, and/orconfiguration. For example, in some embodiments, the sequestrationportion 134 can be at least partially formed by a body portion of thecontrol device 100 (not shown in FIG. 1). In other embodiments, thesequestration portion 134 can be a reservoir placed and/or disposedwithin a portion of the control device 100. In other embodiments, thesequestration portion 134 can be formed and/or defined by a portion ofthe fluid flow path 133. That is to say, the control device 100 candefine one or more lumen and/or can include one or more lumen definingdevice(s) configured to receive a flow of bodily fluid from the inlet132, thereby defining the fluid flow path 133. In such embodiments, atleast a portion of the lumen and/or a portion of the lumen definingdevice(s) can form and/or can define the sequestration portion 134.

The sequestration portion 134 can have any suitable volume and/or fluidcapacity. For example, in some embodiments, the sequestration portion134 can have a volume and/or fluid capacity between about 0.25milliliters (mL) and about 5.0 mL. In some embodiments, thesequestration portion 134 can have a volume measured in volumes as smallas a microliter or less of bodily fluid (e.g., a volume as small as 20drops of bodily fluid, 10 drops of bodily fluid, 5 drops of bodilyfluid, a single drop of bodily fluid, or any suitable volumetherebetween). In other embodiments, the sequestration portion 134 canhave a volume up to, for example, about 5.0 mL, 10.0 mL, 15.0 mL, 20.0mL, 30.0 mL, 40.0 mL, 50.0 mL, or more. In some embodiments, thesequestration portion 134 can have a volume that is equal to and/or thatis based at least in part on the volumes of a lumen of the access orinlet device coupled to and/or included in the control device 100, thelumen of the inlet 132, and a portion of the fluid flow path 133 definedbetween the inlet 132 and the sequestration portion 134 and/or anycombination thereof. In other embodiments, the sequestration portion 134can have a volume that is equal to and/or that is based at least in parton the individual and/or combined volumes of a portion of the access orinlet device, the inlet 132 of the control device 100, and the portionof the fluid flow path 133 defined between the inlet 132 and thesequestration portion 134.

Although not shown in FIG. 1, in some embodiments, the sequestrationportion 134 can include one or more passive or active flow controllers(e.g., shapes, sizes, flow paths, materials configured to interact withfluid, actuators, plungers, pistons, valves, flow restrictors, seals,vents, etc.,) that can be actuated, engaged, manipulated, and/orcontrolled to urge, draw, direct, and/or divert fluid (e.g., bodilyfluid, air or other gases, and/or the like) into or out of thesequestration portion 134. For example, in some embodiments, thesequestration portion 134 can include any suitable arrangement,configuration, and/or feature, and/or can be formed of one or morematerials configured to interact with a portion of the bodily fluidtransferred into the sequestration portion 134. In some embodiments, thecontrol device 100 can include an absorbent and/or hydrophilic materialdisposed within the sequestration portion 134. Accordingly, when bodilyfluid is transferred into the sequestration portion 134, the absorbentand/or hydrophilic material can absorb, attract, retain, expand, and/orotherwise interact with at least a portion of the bodily fluid, which inturn, can sequester and/or retain at least an initial portion of thebodily fluid within the sequestration portion 134, as described infurther detail herein.

In other embodiments, the sequestration portion 134 can include and/orcan be formed of an expandable or collapsible material configured totransition between a first state (e.g., while an initial portion of thebodily fluid is being transferred into the sequestration portion 134) toa second state (e.g., after the initial portion of the bodily fluid istransferred into the sequestration portion 134). In some embodiments, aforce associated with and/or resulting from such a material expanding orcollapsing can be operable to transition the control device 100 and/orany suitable portion of the control device 100 from a first state, mode,position, configuration, etc. to a second state, mode, position,configuration, etc. In some embodiments, the sequestration portion 134and/or any other suitable portion of the control device 100 can includeone or more chemicals, compounds, and/or the like configured tochemically interact with bodily fluid transferred through a portion ofthe control device 100, which can be operable to transition the controldevice 100 between the first state and the second state (e.g., via aforce or any other suitable means).

In some embodiments, the sequestration portion 134 can have a geometryand/or can be formed of a material or can have a material coatingconfigured to wick, attract, absorb, and/or retain, bodily fluid. Forexample, in some embodiments, the geometry of the sequestration portion134 and/or at least a portion thereof can have a geometry configured toenhance wicking such as a high surface area to volume ratio. In otherembodiments, the sequestration portion 134 can have a relatively smallvolume and an elongate perimeter or circumference configured to enhancecapillary action (e.g., wicking) or the like. For example, in someembodiments, the sequestration portion 134 can include and/or can beformed with one or more structures (e.g., a series of capillary tubes)configured to have a high surface area to volume ratio to draw fluidinto the sequestration portion 134. In some embodiments, a forceassociated with these one or more structures (e.g., intermolecularforces acting between the surfaces of the fluid and the structures) canbe operable to wick, attract, absorb, and/or retain, bodily fluid thatis diverted and sequestered in the sequestration portion 134. In someembodiments, the sequestration portion 134 can include a textured orpitted inner surface configured to facilitate absorption, attraction,and/or wicking of bodily fluid. Similarly, in some embodiments, theinner surface of the sequestration portion 134 can have and/or caninclude a coating or the like configured to facilitate wicking,absorption, attraction, etc. (e.g., a hydrophilic coating or the like).

In some embodiments, sequestration portion 134 can include and/or canhouse one or more mechanical actuators that can move or can be movedwithin the sequestration portion 134 to produce changes in volume and/orto produce a pressure differential between the sequestration portion 134and, for example, the fluid source and/or a portion of the fluid flowpath 133 outside of the sequestration portion 134. In other embodiments,the movement of the mechanical actuators can produce a pressuredifferential between the sequestration portion 134 and an ambientenvironment into which the sequestration portion 134 is vented. Forexample, a mechanical actuator can be in an initial state, prior to useof the control device 100, where a pressure differential between thesequestration portion 134 and the source of bodily fluid is based on apositive pressure associated with, for example, the vasculature of thepatient (i.e., blood pressure). In such instances, the pressuredifferential can be relatively small. In some such instances, themechanical actuator can be transitioned from the initial state to asubsequent state upon the start of the flow of the initial volume ofbodily fluid such that the transitioning of the mechanical actuator canvent the air or gaseous contents within the sequestration portion 134 aswell as produce a negative pressure differential between thesequestration portion 134 and the source of bodily fluid, drawing theflow of bodily fluid into the sequestration portion 134. In some suchembodiments, the transitioning of the mechanical actuator can also beconfigured to modify access to one or more openings (not shown inFIG. 1) to allow a flow of air or gas disposed within parts of thesequestration portion 134 through the opening(s). In some embodiments,an amount of movement of the mechanical actuator and/or an equalizationof pressure after the movement of the mechanical actuator can be afactor in determining and/or defining how bodily fluid flows through thecontrol device 100 and/or the amount or volume of bodily fluid to betransferred into the sequestration portion 134, as disclosed in detailbelow with respect to specific embodiments.

In some embodiments, a flow controller(s) (not shown in FIG. 1) can beactivated and/or operated in any suitable manner. For example, in someembodiments, the method of activating a flow controller(s) can bepassive (e.g., automatic, and not requiring user intervention, asdescribed in detail with reference to specific embodiments below). Inother embodiments, the method of activating a flow controller(s) can beactive (e.g., in response to a generated source of energy and/ornegative pressure) and/or via user intervention (e.g., an external forceapplied by a user). In some such embodiments, the sequestration portion134 can include structures or substances that are activated ordeactivated to move or aid in the movement of the actuators from aninitial state to a resulting state. The structures or substances can beactivated by any suitable mechanism, for example, by contact with asmall amount of bodily fluid (or any other fluid), by the passage ofpredetermined amount of time, by changes in pressure or temperature, byexpansion or contraction of a volume, and/or the like. In someembodiments, the initial state can be one in which the flowcontroller(s) or a portion thereof has a high potential energy and anactivation of the flow controller results in conversion of the potentialenergy to kinetic energy. As some examples, activation of substances canbe the reconstitution of dried chemicals producing gaseous substancesthat move the plungers. In other embodiments, activation can includedissolving substances, which in turn, can allow an energy storage memberto release energy to move a plunger (e.g., a spring in tension that isreleased to move the plunger). Specific example embodiments aredescribed in further detail below.

In some embodiments, the control device 100 and/or the sequestrationportion 134 can include and/or define one or more openings (not shown inFIG. 1), as described above, in fluid communication with thesequestration portion 134. That is, in some embodiments, a wall orstructure of the control device 100 can includes and/or define anopening which is either built into or defined by the body of thesequestration portion 134, (e.g., a vent, port, aperture, orifice, etc.,referred to, herein, as “opening”) that is in fluid communication withthe sequestration portion 134. In some embodiments, the opening can beuncovered. In other embodiments, the one or more devices thatselectively control flow of fluids and/or gases can be disposed withinand/or can cover the opening. For example, in some embodiments, theopening can include a mechanical port, valve, membrane, vent, gate,and/or the like (not shown in FIG. 1) configured to permit or restrictfluid (e.g., liquid and/or gas) flow in one or both directions based onits configuration or in response to an external control (e.g., aduckbill valve, a one-way check valve, a stopcock, a ball valve, aporous material, a selectively permeable membrane, a switch, a flowcontroller, a port, a lock, a coupler, etc.). In some other embodiments,for example, the control device 100 can include a material or asemi-permeable member or membrane (not shown in FIG. 1) disposed in orabout the opening to selectively allow a flow of air or gas through theopening while limiting or substantially preventing a flow of fluid(e.g., bodily fluid such as blood) through the opening. Thesemi-permeable member can prevent fluid flow based on any suitablemechanism such as, for example, expansion from saturation and/orabsorption of fluid and/or a change in the viscosity of the absorbedfluid (e.g., bodily fluid). In other embodiments, the control device 100can be configured such that the opening can be operably coupled to asuitable structure or mechanism (not shown in FIG. 1) that selectivelyallows the flow of air or gas through the opening while blocking orsealing off or closing the opening to avoid flow of fluid (e.g., bodilyfluid such as blood).

The opening and/or the semi-permeable member can be configured to “vent”the sequestration portion 134. In some embodiments, the venting of thesequestration portion 134 as an initial portion of the bodily fluid istransferred into the sequestration portion 134 can allow for anequalization of pressure in the sequestration portion 134 and/or betweenthe sequestration portion 134 and, for example, the fluid source and/ora portion of the fluid flow path outside of the sequestration portion134, or a pressure of an ambient environment into which thesequestration portion 134 is vented. In some embodiments, theequalization of pressure can be a factor in determining and/or defininghow bodily fluid flows through the control device 100 and/or the amountor volume of bodily fluid to be transferred into the sequestrationportion 134.

Expanding further, the venting of the sequestration portion 134 canallow a flow of air or gas to pass through the opening or semi-permeablemember in response to being displaced by a flow of bodily fluid. Forexample, in some embodiments, the sequestration portion 134, the fluidflow path 133, and/or at least a portion of an inner volume of thecontrol device 100 can contain a volume of air or gas prior to use. Asbodily fluid flows through the inlet 132 of the control device 100 andenters the fluid flow path 133, the bodily fluid displaces at least aportion of the air or gas contained therein. Moreover, in someembodiments, the at least one outlet 136 of the control device 100 canbe sealed prior to diverting and/or sequestering the initial portion ofbodily fluid. Accordingly, as bodily fluid enters the fluid flow path133 and displaces a volume of air or gas otherwise disposed therein, thesealed arrangement of the at least one outlet forms an air lock or thelike that limits and/or substantially prevents a flow of the bodilyfluid toward the at least one outlet 136. Conversely, the opening and/orsemi-permeable member of the sequestration portion 134 allows for aventing of the sequestration portion 134 in response to the volume ofair or gas being displaced by the bodily fluid. Thus, the venting of thesequestration portion 134 and/or the wicking arrangement as describedabove, facilitates, urges, encourages, draws, and/or otherwise directsan initial flow of the bodily fluid into the sequestration portion 134,as described in further detail herein with respect to specificembodiments.

As described above, in some embodiments, the opening can be and/or canbe included in a port or the like. In some such embodiments, the portcan be configured to couple to any suitable device, reservoir, pressuresource, etc. For example, in some embodiments, the port can beconfigured to couple to an external reservoir, which in turn, can allowa greater volume of bodily fluid to be diverted and/or transferred intothe sequestration portion 134 and the external reservoir, collectively.In other embodiments, the port can be coupled to a negative pressuresource such as an evacuated container, a pump, a syringe, and/or thelike. In other embodiments, the port can be configured to receive aprobe, sampling tool, testing device, and/or the like that can be usedto perform one or more tests (e.g., tests not sensitive to potentialcontamination) on the initial volume while the initial volume isdisposed or sequestered in the sequestration portion 134. In still otherembodiments, the port can be coupled to any suitable infusion deviceconfigured to infuse the initial volume of bodily fluid sequestered inthe sequestration chamber back into the patient and/or bodily fluidsource (e.g., in the case of very sick or low blood volume patient's orthe like). In yet other embodiments, the port can be coupled to theoutlet 136 such that a flow of the initial volume can be transferred toa fluid collection device coupled to the outlet 136 (e.g., aftercollecting the desired sample volume(s) that are substantially free ofcontaminants in a separate fluid collection device).

The at least one outlet 136 of the control device 100 is in fluidcommunication with and/or is configured to be placed in fluidcommunication with the fluid flow path 133. The outlet 136 can be anysuitable outlet, opening, port, stopcock, lock, seal, coupler, valve(e.g., one-way, check valve, duckbill valve, umbrella valve, and/or thelike), etc. and is configured to be fluidically coupled to a fluidcollection device (not shown in FIG. 1). In some embodiments, the outlet136 can be monolithically formed with the fluid collection device. Inother embodiments, the outlet 136 can be at least temporarily coupled tothe fluid collection device via an adhesive, a resistance fit, amechanical fastener, a threaded coupling, a piercing or puncturingarrangement, any number of mating recesses, and/or any other suitablecoupling or combination thereof. Similarly stated, the outlet 136 can bephysically (e.g., mechanically) and/or fluidically coupled to the fluidcollection device such that an interior volume defined by the fluidcollection device is in fluid communication with the outlet 136. Instill other embodiments, the outlet 136 can be operably coupled to thefluid collection device via an intervening structure (not shown in FIG.1), such as a flexible sterile tubing. As described above, in someembodiments, the arrangement of the at least one outlet 136 can be suchthat the outlet 136 is physically and/or fluidically sealed and/orotherwise fluidically isolated from at least a portion of the fluid flowpath 133 prior to coupling to the fluid collection device. In someembodiments, such a sealed arrangement can facilitate, direct, and/orotherwise result in an initial flow of bodily fluid into thesequestration portion 134 rather than the outlet 136.

The fluid collection device can be any suitable device for receivingand/or at least temporarily containing a bodily fluid, such as, forexample, any of those described above. In some embodiments, the fluidcollection device can be a single-use disposable collection tube(s), avacuum-based collection tube(s), and/or the like. For example, in someembodiments, the fluid collection device can be substantially similar toor the same as known sample containers such as, for example, aVacutainer® (manufactured by BD), a BacT/ALERT® SN or BacT/ALERT® FA(manufactured by Biomerieux, Inc.), and/or any suitable reservoir, vial,microvial, microliter vial, nanoliter vial, container, microcontainer,nanocontainer, and/or the like. In some embodiments, the fluidcollection device can include a vacuum seal that maintains negativepressure conditions (vacuum conditions) inside the fluid collectiondevice, which in turn, can facilitate withdrawal of bodily fluid fromthe patient, through the control device 100, and into the fluidcollection device, via a vacuum or suction force. In embodiments inwhich the fluid collection device is an evacuated container or the like,the user can couple the fluid collection device to the outlet 136 afterthe initial portion of the bodily fluid is transferred into and/orsequestered by the sequestration portion 134, which in turn, can limitand/or substantially prevent an initial portion of the bodily fluid(potentially containing contaminants) from being transferred into thefluid collection device, as described in further detail herein.

Although the outlet 136 of the control device 100 is described above asbeing fluidically coupled to and/or otherwise placed in fluidcommunication with the fluid collection device, in other embodiments,the control device 100 can be used in conjunction with any suitablebodily fluid collection device and/or system. For example, in someembodiments, the control device 100 described herein can be used in anysuitable fluid transfer device such as those described in U.S. PatentPublication No. 2015/0342510 entitled, “Sterile Bodily-Fluid CollectionDevice and Methods,” filed Jun. 2, 2015 (referred to herein as the “'510publication”), the disclosure of which is incorporated herein byreference in its entirety and attached hereto as Exhibit B. Moreparticularly, the control device 100 can be used in an “all-in-one” orpre-assembled device (e.g., such as those described in the '510publication) to receive and sequester an initial volume of bodily fluidsuch that contaminants in subsequent volumes of bodily fluid are reducedand/or eliminated.

As described above, in some embodiments, the device 100 can be used toprocure a bodily fluid sample having reduced contamination from microbessuch as, for example, dermally residing microbes and/or the like. Forexample, in some instances, a user such as a doctor, physician, nurse,phlebotomist, technician, etc. can manipulate the device 100 toestablish fluid communication between the inlet device and the bodilyfluid source (e.g., a vein of a patient, cerebral spinal fluid (CSF)from the spinal cavity, urine collection, and/or the like). As aspecific example, in some instances, the inlet device can include aneedle or the like that can be manipulated to puncture the skin of thepatient and to insert at least a portion of the needle in the vein ofthe patient, thereby placing the inlet device in fluid communicationwith the bodily fluid source (e.g., the vein). In other instances, thedevice 100 can be used to transfer a bodily fluid sample having reducedcontamination from microbes such as, for example, microbes residing onpartially or incompletely sterilized transfer devices, surfaces,interfaces, personnel, and/or the like.

In some embodiments, once the inlet 132 is placed in fluid communicationwith the bodily fluid source (e.g., the portion of the patient, or acontainer), the outlet 136 can be fluidically coupled to the fluidcollection device. As described above, in some embodiments, the fluidcollection device can be any suitable reservoir, container, and/ordevice configured to receive a volume of bodily fluid. For example, thefluid collection device can be an evacuated reservoir or container thatdefines a negative pressure and/or can be a syringe that can bemanipulated to produce a negative pressure. In some instances, couplingthe outlet 136 to the fluid collection device selectively exposes atleast a portion of the fluid flow path 133 to the negative pressure,thereby resulting in a negative pressure differential operable indrawing bodily fluid from the bodily fluid source (e.g., the patient),through the inlet 132, and into at least a portion of the fluid flowpath 133.

The control device 100 can be coupled to the inlet device before orafter the inlet device is placed in fluid communication with the bodilyfluid source. In other embodiments, the inlet 132 of the control device100 includes, forms, and/or is monolithically formed with the inletdevice. Thus, by coupling or forming the inlet 132 to or with the inletdevice, establishing fluid communication between the inlet device andthe bodily fluid source places the control device 100 in fluidcommunication with the bodily fluid source. Thus, bodily fluid can flowfrom the bodily fluid source (e.g., the vein of the patient, or acollection device or reservoir), through the inlet device, and/or atleast through the inlet 132, and into the flow path 133 of the controldevice 100.

As described above, the fluid flow path 133 of the control device 100establishes fluid communication between the inlet 132 and thesequestration portion 134 and/or the outlet 136. In some embodiments,the arrangement of the control device 100 is such that when a volume ofbodily fluid is transferred to and/or through the inlet 132, an initialportion of the volume of bodily fluid (also referred to herein as an“initial volume” or a “first volume”) flows from the inlet 132, throughat least a portion of the fluid flow path 133, and into thesequestration portion 134. That is to say, in some embodiments, thecontrol device 100 can be in first or initial state in which the initialportion or volume of bodily fluid can flow in or through at least aportion the fluid flow path 133 and into the sequestration portion 134.For example, in some embodiments, the initial state of the controldevice 100 can be one in which the sequestration portion 134 is ventedand the outlet 136 is sealed and/or otherwise fluidically isolated fromthe inlet 132. As such, bodily fluid entering the fluid flow path 133displaces a volume of air or gas otherwise disposed therein, which inturn, is released, expelled, and/or vented through the sequestrationportion 134 to a volume outside of the sequestration portion 134 (e.g.,to the ambient environment). As such, the venting urges, draws, and/orotherwise diverts the initial portion of the bodily fluid into thesequestration portion 134 prior to the bodily fluid flowing to theoutlet 136.

The initial portion and/or amount of bodily fluid can be any suitablevolume of bodily fluid, as described above. For example, in someinstances, the control device 100 can remain in the first state until apredetermined and/or desired volume (e.g., the initial volume) of bodilyfluid is transferred to the sequestration portion 134. In someembodiments, the initial volume can be associated with and/or at leastpartially based on a volume of the sequestration portion 134 and/or abladder, bag, container, chamber, volume, etc. disposed therein. In someembodiments that include one or more flow controllers, the initialvolume can be associated with and/or at least partially based on avolume of bodily fluid sufficient to transition the one or more flowcontrollers from a first state and/or configuration to a second stateand/or configuration.

For example, in some embodiments, the initial volume can be associatedwith and/or at least partially based on an amount or volume of bodilyfluid that can be absorbed by an absorbent material, an expandablematerial, a hydrophilic material, a wicking material, and/or othersuitable material (e.g., the material of one or more flow controllers)disposed in the sequestration portion 134. Further, as an example, theabsorbent material when sufficiently saturated can affect the pressuredifferential between the sequestration portion 134 and the fluid flowpath 133 and/or the bodily fluid source, placing the sequestrationportion 134 in the sealed state. Similarly, the initial volume can beassociated with and/or at least partially based on an amount or volumeof bodily fluid that is sufficient to fully wet or saturate asemi-permeable member or membrane otherwise configured to vent thesequestration portion 134 (e.g., the sequestration portion 134 istransitioned from a “venting” state to a “sealed” state or the like).

In some embodiments, the control device 100 can be configured totransfer a volume of bodily fluid (e.g., the initial volume) into thesequestration portion 134 until a pressure differential between thesequestration portion 134 and the fluid flow path 133 and/or the bodilyfluid source is brought into substantial equilibrium, substantialequalization, and/or is otherwise reduced below a desired threshold. Inembodiments including a flow controller such as, for example, one ormore mechanical actuators (e.g., a plunger), an amount of movementand/or travel of the mechanical actuator can determine the resultantvolume and/or pressure (or changes thereof) of or in the sequestrationportion 134. In such embodiments, the initial portion of bodily fluidcan be an amount sufficient to fill the volume and/or to substantiallyequalize the pressure differential (or at least reduce the pressuredifferential below a threshold level) generated by the change inconfiguration of the mechanical actuator. In other embodiments, theinitial volume can be any suitable volume based on any combination offeatures and/or characteristics of the control device 100.

After the initial volume of bodily fluid is transferred and/or divertedinto the sequestration portion 134, the initial volume is sequestered,segregated, retained, contained, isolated, etc. in the sequestrationportion 134. For example, in some embodiments, the wicking and/orabsorbent configuration of the sequestration portion 134 (and/or a flowcontroller disposed therein) can be configured to retain the initialvolume of bodily fluid in the sequestration portion 134 despite one ormore changes in other portions of the control device 100 (e.g., theopening of the outlet 136 and/or the like). In some embodiments, one ormore portions of the flow path 133 allowing fluid communication betweenthe inlet 132 and the sequestration portion 134 and/or between the inlet132 and the outlet 136, can include one or more flow controllers such asone-way valves (e.g., check valves, duckbill valves etc.) that permitfluid flow in one direction (e.g., from the inlet 132 towards thesequestration portion 134) but not the other (e.g., from thesequestration portion 134 towards the outlet 136 or towards the inlet132). For example, in some embodiments, transferring the initial volumeof bodily fluid into the sequestration portion 134 in conjunction withthe functioning of a one-way valve preventing back flow of fluid fromthe sequestration portion 134 can place the sequestration portion 134 inthe sealed and/or sequestered state. In some such embodiments, access tothe fluid collection device (via the outlet 136) and/or a negativepressure within the fluid collection device can be operable in sealingone or more valves, thereby placing the sequestration portion 134 in thesealed and/or sequestered state. As such, the sequestration portion 134can sequester and/or retain the initial portion of the bodily fluid inthe sequestration portion 134. As described in further detail herein, insome instances, contaminants such as, for example, dermally residingmicrobes or the like dislodged during the venipuncture event, can beentrained and/or included in the initial volume of the bodily fluid andthus, are sequestered in the sequestration portion 134 when the initialvolume is sequestered therein.

With the initial volume transferred and/or diverted into thesequestration portion 134, the device 100 can transition to the secondstate in which a subsequent volume(s) of bodily fluid can flow throughat least a portion the fluid flow path 133 from the inlet 132 to theoutlet 136. In some embodiments, the control device 100 can passivelyand/or automatically transition (e.g., without user intervention) fromthe first state to the second state once the initial volume of bodilyfluid is sequestered in the sequestration portion 134. For example, insome embodiments, filling the sequestration portion 134 to capacityand/or fully saturating, wetting, and/or impregnating an absorbent orsimilar material disposed in the sequestration portion 134 can be suchthat further transfer of bodily fluid into the sequestration portion 134is limited and/or substantially prevented. In other embodiments, thecontrol device 100 can be manually transitioned or transitioned inresponse to at least an indirect interaction by a user. For example, insome embodiments, a user can at least partially obstruct the openingand/or vent of the sequestration portion 134, which in turn, can limitand/or substantially prevent additional flow of bodily fluid fromentering and/or from being transferred into the sequestration portion134. In other embodiments, the user can actuate an actuator or the like(not shown in FIG. 1) to transition the control device 100 from thefirst state to the second state. In still other embodiments, at least aportion of the initial volume of bodily fluid can transition the controldevice 100 from the first state to the second state. For example, thecontrol device 100 can include a bodily fluid activated flow controllersuch as a switch, valve, port, and/or the like. In other embodiments, avolume of bodily fluid can move and/or displace one or more flowcontrollers such as actuators or the like that can, for example, open aport, flow path, and/or outlet. In still other embodiments, a user canmanipulate a flow controller such as a switch, valve, port, actuator,etc. to transition the control device 100 from the first state to thesecond state.

The fluid collection device (not shown in FIG. 1) can be at leastfluidically coupled to the outlet 136 before or after the control device100 is placed in the second state. In some embodiments, the arrangementof the outlet 136 can be such that the outlet 136 (or portion of thefluid flow path 133 leading to the outlet 136) remains sealed until theinitial volume of bodily fluid is sequestered in the sequestrationportion 134 regardless of whether the fluid collection device is coupledto the outlet 136. Accordingly, with the fluid collection devicefluidically coupled to the outlet 136 and with the control device 100being in the second state (e.g., the initial volume of bodily fluid issequestered in or by the sequestration portion 134), any subsequentvolume(s) of the bodily fluid can flow from the inlet 132, through thefluid flow path 133 and the outlet 136, and into the fluid collectiondevice. Thus, as described above, sequestering the initial volume ofbodily fluid in the sequestration portion 134 prior to collecting orprocuring one or more sample volumes of bodily fluid reduces and/orsubstantially eliminates an amount of contaminants in the one or moresample volumes. Moreover, in some embodiments, the arrangement of thecontrol device 100 can be such that control device 100 cannot transitionto the second state prior to collecting and sequestering the initialvolume in the sequestration portion 134.

FIGS. 2-4 illustrate a fluid control device 200 according to anembodiment. As described above with reference to the control device 100,the fluid control device 200 (also referred to herein as “controldevice” or “device”) is configured to withdraw and sequester a firstportion or amount (e.g., an initial amount) of bodily fluid from apatient or other bodily fluid source, and subsequently withdraw a secondportion or amount (e.g., a subsequent amount) of bodily fluid for use,for example, in bodily fluid sampling and/or testing. By sequesteringthe first portion or amount of bodily fluid, contaminants or the likesuch as, for example, dermally residing microbes dislodged duringvenipuncture and/or microbes residing on incompletely sterilizedtransfer devices, surfaces, and/or interfaces are similarly sequestered,leaving the second portion or amount of bodily fluid substantially freeof contaminants. In some embodiments, portions and/or aspects of thecontrol device 200 are substantially similar in form and/or function tothe corresponding portions and/or aspects of the control device 100described above with reference to FIG. 1. Accordingly, such similarportions and/or aspects are not described in further detail herein.

As shown in FIG. 2, the control device 200 includes an inlet device 210and a housing 230 in fluid communication with and/or configured to beplaced in fluid communication with the inlet device 210. In general, theinlet device 210 can be any suitable device or set of devices configuredto establish fluid communication between the housing 230 and a bodilyfluid source such as, for example, the vasculature of a patient or areservoir of collected bodily fluid. The housing 230 of the controldevice 200 can be any suitable device or set of devices configured to(1) receive a flow of bodily fluid, (2) store and sequester, segregate,retain, contain, isolate, etc., a first volume or initial volume of thebodily fluid, and (3) direct or divert a subsequent flow of the bodilyfluid to a fluid collection device, as described in further detailherein.

The inlet device 210 can be any suitable device(s) such as, for example,an IV catheter, a sharpened catheter or sharpened needle, and/or anyother suitable lumen-containing device. While illustrated as a needlefor procuring fluids directly from a patient (e.g., from a vasculatureof the patient) in FIGS. 2-4, the inlet device 210 can in otherembodiments be configured to obtain fluid from a reservoir or containeror the like of bodily fluid collected from a patient. The inlet devicein some instances can include suitable ports or couplers or the likethat can be connected to corresponding ports or couplers or the like ofa reservoir containing collected bodily fluid or to corresponding portsor couplers of transfer apparatus that may in turn be connected acollected source of bodily fluid. In some embodiments, the inlet deviceto couple with a transfer apparatus or a reservoir of collected fluid,can include associated structures and/or control devices to operate theinlet device to control the fluidic communication between the inletdevice and the source of bodily fluid. For example, in the embodimentshown in FIGS. 2-4, the inlet device 210 is a butterfly needle or othersuitable access device having a body 211, a needle 214, and a flexibletubing 220. As shown in FIG. 4, the body 211 defines a lumen 212extending through the body 211, the needle 214 defines a lumen 215extending through the needle 214, and the flexible tubing 220 defines alumen 221 extending through the flexible tubing 220. The needle 214 iscoupled to, for example, a distal end portion of the body 211 such thatthe lumen 215 of the needle 214 is in fluid communication with the lumen212 of the body 211. Likewise, the flexible tubing 220 is coupled to,for example, a proximal end portion of the body 211 such that the lumen221 of the flexible tubing 220 is in fluid communication with the lumen212 of the body 211. Thus, the lumen 215 of the needle 214, the lumen212 of the body 211, and the lumen 221 of the flexible tubing 220collectively define a fluid flow path extending through the inlet device210.

In the embodiment shown in FIGS. 2-4, the housing 230 of the controldevice 200 includes a body 231 having an inlet 232 and an outlet 236,and defines a fluid flow path 233 and a sequestration and/or diversionportion 234 (also referred to herein as “sequestration portion”). Thebody 231 of the housing 230 can be any suitable shape, size, and/orconfiguration. For example, in some embodiments, the body 231 can beformed of a relatively rigid material such as a plastic or the like andcan be configured to retain its shape and/or form when exposed tochanges in pressure and/or inlet and outlet flows of fluid. As shown inFIGS. 2 and 4, the inlet 232 formed by the body 231 is physically andfluidically coupled to an end portion of the flexible tubing 220 (e.g.,the flexible tubing 220 is a flexible inlet tubing for the housing 230).A portion of the fluid flow path 233 extends through the inlet 232 ofthe housing 230 such that the coupling of the inlet 232 to the flexibletubing 220 establishes fluid communication between the inlet device 210and the fluid flow path 233. Thus, the housing 230 can receive a flow ofbodily fluid from the inlet device 210, as described in further detailherein.

The fluid flow path 233 extends through the inlet 232 and places theinlet 232 in fluid communication with the sequestration portion 234 andthe outlet 236. In other words, a first portion of the fluid flow path233 extends and/or is defined between the inlet 232 and thesequestration portion 234 and a second portion of the fluid flow path233 extends and/or is defined between the inlet 232 and the outlet 236.In some embodiments, the fluid flow path 233 can be a single, continuousfluid flow path including the first portion and the second portion. Inother embodiments, the housing 230 can be configured to selectivelydirect, divert, and/or control (e.g., via an automatic oruser-controlled actuator or flow controller such as a valve, membrane,and/or the like) a flow of bodily fluid through the first portion or thesecond portion of the fluid flow path 233.

The sequestration portion 234 of the housing 230 is at least temporarilyplaced in fluid communication with the inlet 232 via the fluid flow path233. As described in further detail herein, the sequestration portion234 is configured to (1) receive a flow and/or volume of bodily fluidfrom the inlet 232 and (2) sequester (e.g., separate, segregate,contain, retain, isolate, etc.) the flow and/or volume of bodily fluidtherein. The sequestration portion 234 can be any suitable shape, size,and/or configuration. For example, in the embodiment shown in FIGS. 2-4,the sequestration portion 234 is at least partially formed by the body231 of the housing 230. More particularly, the sequestration portion 234is offset from and/or non-coaxial with an axis defined by the lumen 221of the flexible tubing 221. In other words, the sequestration portion234 is not “in-line” between the inlet 232 and the outlet 236. Forexample, as shown in FIG. 4, the fluid flow path 233 splits, forks,divides, and/or the like into a first portion configured to place thesequestration portion 234 in fluid communication with the inlet 232 anda second portion configured to place the outlet 236 in fluidcommunication with the inlet 232.

The sequestration portion 234 and/or a portion of the body 231 definingand/or forming the sequestration portion 234 further includes and/ordefines an opening 235 (e.g., a vent opening or the like) in fluidcommunication with the sequestration portion 234. As described in detailabove with reference to the sequestration portion 134, the sequestrationportion 234 can have any suitable volume and/or fluid capacity (e.g.,from one or more drops of bodily fluid to 50 mL or more of bodilyfluid). In other embodiments, the sequestration portion 234 can have avolume that is equal to and/or that is based at least in part on thecombined volumes of the lumens 212, 215, and 212 of the inlet device 210and the volume of the portion of the fluid flow path 233 defined betweenthe inlet 232 of the housing 230 and the sequestration portion 234. Assuch, transferring bodily fluid into the sequestration portion 234flushes the lumens 212, 215, and 221 and the fluid flow path 233, whichin turn, can remove and/or sequester prior contaminants containedtherein.

The sequestration portion 234 can include and/or can house one or moreflow controllers or the like configured to interact with the bodilyfluid transferred into the sequestration portion 234. For example, asshown in FIG. 4, the sequestration portion 234 can include one or morematerials configured to interact with the bodily fluid. The one or morematerials can be any suitable configuration such as the configurationdescribed above with reference to the sequestration portion 134. Forexample, in the embodiment shown in FIGS. 2-4, the housing 230 includesa hydrophilic material 240 (e.g., foam, sintered plastic,bodily-fluid-absorbing material, and/or the like) and a vent material242 (e.g., a selectively permeable material) disposed within thesequestration portion 234. Accordingly, when bodily fluid is transferredinto the sequestration portion 234, the hydrophilic material 240 canabsorb, attract, urge, draw, retain, expand, and/or otherwise interactwith at least a portion of the bodily fluid, which in turn, cansequester and/or retain at least an initial portion of the bodily fluidwithin the sequestration portion 234, as described in further detailherein. In other words, the hydrophilic material 240 can be a flowcontroller or the like configured to enhance and/or facilitate wicking,which in turn, can draw bodily fluid into the sequestration portion 234.

The vent material 242 can be configured to vent the sequestrationportion 234 via the opening 235 to allow, enhance, facilitate, and/orotherwise urge the flow of bodily fluid into the sequestration portion234. The arrangement of the vent material 242 can be such that thebodily fluid wets the vent material 242 as the bodily fluid istransferred into the sequestration portion 234. In response to thewetting, the vent material 242 can swell and/or can otherwise cantransition from a configuration and/or state in which the vent material242 vents the sequestration portion 234 to a configuration and/or statein which the vent material 242 seals the sequestration portion 234. Thatis to say, the vent material 242 can be a self-sealing materialconfigured to selectively allow a flow of gas (e.g., air) to vent fromthe sequestration portion 234 through the opening 235.

In some instances, the wetting or transitioning of the vent material 242is associated with and/or correlates to an amount or volume of bodilyfluid transferred to the sequestration portion 234. For example, in someembodiments, the vent material 242 can be placed in and/or cantransition to a fully sealed configuration or state when a predeterminedand/or desired volume of bodily fluid is transferred into thesequestration portion 234 (e.g., the initial portion or initial volume).In some embodiments, the sequestration portion 234 can sequester and/orretrain the predetermined and/or desired volume of bodily fluid in thesequestration portion 234 in response to the vent material 242transitioning to the fully sealed configuration. Moreover, when the ventmaterial 242 is in the fully sealed state and/or when the initialportion of bodily fluid is transferred to the sequestration portion 234,the housing 230 can transition (e.g., passively and/or automatically)from a first state to a second state, in which bodily fluid flowsthrough the fluid flow path 233 to the outlet 236.

Both the hydrophilic material 240 and the vent material 242 can be anysuitable shape, size, and/or configuration. In some embodiments, thehydrophilic material 240 and the vent material 242 can be substantiallysimilar to the hydrophilic or wicking material and the selectivelypermeable member or membrane, respectively, described above withreference to the sequestration portion 134 shown in FIG. 1. While thehydrophilic material 240 and the vent material 242 are shown anddescribed herein as being separate components and/or members, in someembodiments, a sequestration portion can include a single piece ofhydrophilic material that can form and/or can act as the hydrophilicmaterial 240 and the vent material 242. In other embodiments, thehydrophilic material 240 and the vent material 242 can be coupled duringmanufacturing and/or otherwise co-formed or unitarily formed.Accordingly, the hydrophilic material 240 and the vent material 242 canindependently or collectively form a flow controller configured toselectively control fluid flow into and/or out of the sequestrationportion 234.

The outlet 236 formed and/or included in the body 231 is configured tobe placed (directly or indirectly) with any suitable fluid collectiondevice (not shown). For example, in some embodiments, the outlet 236 canbe physically and fluidically coupled directly to the fluid collectiondevice. In other embodiments, the outlet 236 can be indirectly coupledand/or otherwise placed in fluid communication with the fluid collectiondevice via any suitable intervening structure (e.g., a port, conduit,rigid or flexible tube, adapter, etc.). In the embodiment shown in FIGS.2-4, for example, the outlet 236 can be physically and fluidicallycoupled to a flexible outlet tubing 247. The outlet 236 can be anysuitable outlet, opening, port, lock, seal, coupler, etc. and is influid communication with a lumen 248 of the flexible outlet tubing 247,which in turn, places the lumen 248 of the flexible outlet tubing 247 influid communication with the fluid flow path 233. The outlet 236 can becoupled to the flexible outlet tubing 247 (also referred to herein as“outlet tubing”) via any suitable connection, fit, adhesive, etc.

Although not shown in FIGS. 2-4, an end portion of the outlet tubing 247(e.g., opposite the end portion coupled to the outlet 236) is configuredto establish fluid communication between the lumen 248 of the outlettubing 247 and a fluid collection device (not shown). For example, insome embodiments, the end portion of the outlet tubing 247 can includeand/or can be coupled to an outlet needle or the like. In otherembodiments, the outlet tubing 247 can be coupled to a transfer adapterand/or the like such as, for example, the transfer adapters described inU.S. Patent Publication No. 2015/0246352 (referred henceforth as the'352 publication) entitled, “Apparatus and Methods for Disinfection of aSpecimen Container,” filed Mar. 3, 2015, the disclosure of which isincorporated herein by reference in its entirety. Accordingly, theoutlet tubing 247 can place the outlet 236 of the housing 230 in fluidcommunication with the fluid collection device (not shown). As describedabove with reference to the outlet 136 of the housing 130, the outlet236 of the housing 230 can be in a sealed or closed configuration whenthe housing 230 is in a first state and can be transitioned to an openconfiguration when the housing 230 is transitioned to a second state.The fluid collection device can be any suitable reservoir and/orcontainer such as the fluid collection device described above withreference to the control device 100 and thus, is not described infurther detail herein.

As described in detail above with reference to the device 100, thedevice 200 can be used to divert, sequester, isolate, retain (e.g.,passively divert) etc., a first or initial volume of bodily fluid suchthat subsequently procured or transferred bodily fluid samples havereduced contamination from microbes such as, for example, dermallyresiding microbes or microbes residing on incompletely sterilizedtransfer apparatus and/or the like. For example, in some instances, auser such as a doctor, physician, nurse, phlebotomist, technician, etc.can manipulate the device 200 by inserting at least a portion of theneedle 214 into a patient's vein (e.g., a venipuncture event) or acontainer of collected bodily fluid and/or can otherwise establish fluidcommunication between the needle 214 and the source of bodily fluid.Once in fluid communication with the source of bodily fluid, the fluidcan flow from the bodily fluid source (e.g., the vein of the patient, ora container of collected bodily fluid), through the inlet device 210,and into the housing 230. In some embodiments, the housing 230 can be inand/or can be placed in a first or initial state in which an initialportion or volume of bodily fluid can flow in or through at least aportion the fluid flow path 233 and into the sequestration portion 234.

The initial portion and/or volume of bodily fluid can be any suitablevolume of bodily fluid, as described above. For example, in someinstances, the housing 230 can remain in the first state until apredetermined and/or desired volume (e.g., the initial volume) of bodilyfluid is transferred to the sequestration portion 234. In the embodimentshown in FIGS. 2-4, the initial volume can be associated with and/or atleast partially based on an amount or volume of bodily fluid that can beabsorbed by the hydrophilic material 240 (e.g., flow controller).Furthermore, the initial volume can be associated with and/or at leastpartially based on the vent material 242 transitioning to a sealedconfiguration, as described above. In some embodiments, the hydrophilicmaterial 240 becoming saturated (e.g., after absorbing a maximum amountor bodily fluid or substantially a maximum amount) and the vent material242 (e.g., flow controller) becoming saturated (e.g., such that the ventmaterial 242 transitions to the sealed configuration) can occursubstantially concurrently in response to the same, predetermined volumeof bodily fluid being transferred into the sequestration portion 234(i.e., the initial volume). After the initial volume of bodily fluid istransferred and/or diverted into the sequestration portion 234, theinitial volume is sequestered, segregated, retained, contained,isolated, etc. in the sequestration portion 234. As described above,contaminants such as, for example, dermally residing microbes or thelike dislodged during the venipuncture event, can be entrained and/orincluded in the initial volume of the bodily fluid and thus, can also besequestered in the sequestration portion 234 when the initial volume issequestered therein.

With the initial volume sequestered in the sequestration portion 234,the device 200 can transition to the second state in which a subsequentvolume(s) of bodily fluid can flow through at least a portion the fluidflow path 233 from the inlet 232 to the outlet 236. In the embodimentshown in FIGS. 2-4, the housing 230 is configured to automaticallytransition (e.g., without user intervention) from the first state to thesecond state once the initial volume of bodily fluid is sequestered inthe sequestration portion 234. For example, filling the sequestrationportion 234 to capacity and/or fully saturating, wetting, and/orimpregnating the hydrophilic material 240 and/or the vent material 242can limit and/or substantially prevent any additional volume of bodilyfluid from being transferred into the sequestration portion 234. Inaddition, fully saturating, wetting, and/or impregnating the hydrophilicmaterial 240 and/or the vent material 242 can limit and/or substantiallyprevent any fluid flow out of the sequestration portion 234 and into thefluid flow path 233. Thus, as a subsequent flow and/or volume of bodilyfluid enters the fluid flow path 233, the housing 230 directs and/ordiverts the flow through a portion of the fluid flow path 233 and to theoutlet 236.

Although not shown in FIGS. 2-4, the outlet tubing 247 can be at leastfluidically coupled to the fluid collection device before or after thehousing 230 transitions to the second state. In some embodiments, thearrangement of the outlet 236 can be such that the outlet 236 remainssealed until the initial volume of bodily fluid is sequestered in thesequestration portion 234 regardless of whether the fluid collectiondevice is coupled to the outlet 236 and/or the outlet tubing 247.Accordingly, with the fluid collection device fluidically coupled to theoutlet tubing 247 and with the housing 230 being in the second state,any subsequent volume(s) of the bodily fluid can flow from the inlet232, through the fluid flow path 233 and the outlet 236, and into thefluid collection device. Thus, as described above, sequestering theinitial volume of bodily fluid in the sequestration portion 234 prior tocollecting or procuring one or more sample volumes of bodily fluidreduces and/or substantially eliminates an amount of contaminants in theone or more sample volumes. Moreover, in some embodiments, thearrangement of the housing 230 can be such that housing 230 directsand/or diverts the flow into the sequestration portion 234 prior todirecting and/or diverting the flow to the outlet 236. In other words,the housing 230 is configured to force compliance such that the housing230 cannot transition to the second state prior to collecting andsequestering the initial volume in the sequestration portion 234.

While the housing 230 is shown and described above as having thehydrophilic material 240 and the vent material 242 disposed in thesequestration portion 234, that can be flow controllers, in otherembodiments, a portion of a control device can include a sequestrationportion having any suitable configuration. For example, as describedabove with reference to the sequestration portion 134, in someembodiments, the sequestration portion 234 can include a hydrophiliccoating or surface finish and/or any other suitable flow controller(s).In other embodiments, the sequestration portion 234 can have a geometryor the like configured to enhance and/or facilitate wicking and/orabsorption, configured to act as flow controllers. While the ventmaterial 242 is described as being an absorbent material and/or aselectively permeable member or membrane, in other embodiments, thesequestration portion 234 can include a vent that is formed with or by aone-way valve or the like. In some embodiments, such a valve can be gaspermeable and liquid impermeable. In some embodiments, such a valve canbe user actuated, fluid actuated, pressure actuated, time-based, etc. Insome embodiments, the sequestration portion 234 can include a one-wayvalve and the vent material 242 that can collectively act to vent thesequestration portion 234. In such embodiments, the one-way valve can bedisposed in any suitable position relative to the vent material 242(e.g., upstream or downstream relative to the vent material 242).

FIGS. 5 and 6 illustrate a fluid control device 300 according to anembodiment. As described above with reference to the control devices 100and 200, the fluid control device 300 (also referred to herein as“control device” or “device”) is configured to withdraw and sequester afirst portion or amount (e.g., an initial amount) of bodily fluid from apatient such that any subsequently withdrawn amount, portion, and/orvolume of bodily fluid is substantially free of contaminants. In someembodiments, portions and/or aspects of the control device 300 aresubstantially similar in form and/or function to the correspondingportions and/or aspects of the control devices 100 and/or 200 describedabove with reference to FIG. 1 and FIGS. 2-4, respectively. Accordingly,such similar portions and/or aspects are not described in further detailherein.

As shown in FIG. 5, the control device 300 includes an inlet device 310and a housing 330 in fluid communication with and/or configured to beplaced in fluid communication with the inlet device 310. The inletdevice 310 can be any suitable device(s) such as, for example, an IVcatheter, a sharpened catheter or sharpened needle, a coupler, a port, aconnector, and/or any other suitable lumen-containing device. In theembodiment shown in FIGS. 5 and 6, the inlet device 310 is a butterflyneedle or other suitable access device having a body 311, a needle 314,and a flexible tubing 320. Moreover, the inlet device 310 is similar toand/or substantially the same as the inlet device 210 described indetail above with reference to FIGS. 2-4. Thus, the inlet device 310 isnot described in further detail herein. As described above withreference to the inlet device 210 of the control device 200, whileillustrated as a needle for procuring fluids directly from a patient(e.g., from a vasculature of the patient) in FIGS. 5-6, the inlet device310 can in other embodiments be configured to obtain fluid from areservoir or container or the like of bodily fluid collected from apatient. The inlet device in some instances can include suitable portsor couplers or the like that can be connected to corresponding ports orcouplers or the like of a reservoir containing collected bodily fluid orto corresponding ports or couplers of transfer apparatus that may inturn be connected a collected source of bodily fluid. In someembodiments, the inlet device to couple with a transfer apparatus or areservoir of collected fluid, can include associated structures and/orcontrol devices to operate the inlet device to control the fluidiccommunication between the inlet device and the source of bodily fluid.

The housing 330 includes a body 331 having an inlet 332 and an outlet336, and defines a fluid flow path 333 and a sequestration and/ordiversion portion 334 (also referred to herein as “sequestrationportion”). The body 331 of the housing 330 can be any suitable shape,size, and/or configuration. For example, in some embodiments, the body331 can be formed of a relatively rigid material such as a plastic orthe like and can be configured to retain its shape and/or form whenexposed to changes in pressure and/or inlet and outlet flows of fluid.As shown in FIGS. 5 and 6, the body 331 forms and/or includes the inlet332, which is physically coupled to an end portion of the flexibletubing 320 and fluidically coupled to the inlet device 310 via a lumen321 defined by the flexible tubing 320 (e.g., the flexible tubing 320 isa flexible inlet tubing for the housing 330). Likewise, the body 331forms and/or includes the outlet 336, which is physically andfluidically coupled to a flexible outlet tubing 347 (and/or any othersuitable medical tubing, coupler, and/or intermediate conduit) thatdefines a lumen 348 configured to place the outlet in fluidcommunication with a fluid collection device (not shown). Thesequestration portion 334 is offset from and/or non-coaxial with theinlet 332 and, as such, the fluid flow path 333 extends through aportion of the body 331 to fluidically couple the inlet 332 to thesequestration portion 334 and the outlet 336. Accordingly, the housing330 can be similar in at least form or function to the housing 230described in detail above with reference to FIGS. 2-4 and thus, portionsand/or aspects of the housing 330 are not described in further detailherein.

The housing 330 can differ from the housing 230 of the control device200, however, in the arrangement of the sequestration portion 334. Forexample, while the housing 230 included the hydrophilic material 240 andthe vent material 242 disposed in the sequestration portion 234, thehousing 330 includes an expandable bladder 343 (e.g., a flow controllerand/or the like) disposed in the sequestration portion 334, as shown,for example, in FIG. 6. In some embodiments, the expandable bladder 343disposed in the sequestration portion 334 can be sealed, closed, and/orotherwise not vented while a volume of the sequestration portion 334outside of the expandable bladder 343 is vented and/or otherwise definesan opening configured to vent a volume of the sequestration portion 334that is outside of and/or surrounding the expandable bladder 343. Insome embodiments, the closed arrangement of the expandable bladder 343can be such that the opening need not include a selectively permeablemember or membrane to prevent the venting or escaping of bodily fluid.In other embodiments, the sequestration portion 334 can include a ventmaterial, valve, and/or the like, as described above with reference tothe housing 230. The sequestration portion 334 and more specifically, aninner volume of the expandable bladder 343 disposed therein is at leasttemporarily placed in fluid communication with the inlet 332 via thefluid flow path 333 and is configured to (1) receive a flow and/orvolume of bodily fluid from the inlet 332 and (2) sequester (e.g.,separate, segregate, contain, retain, isolate, etc.) the flow and/orvolume of bodily fluid therein. As described in further detail herein,the sequestration portion 334 can be configured to vent a volume of thesequestration portion 334 that is outside of and/or surrounding theexpandable bladder 343 as the flow and/or volume of bodily fluid istransferred into the expandable bladder 343, which in turn, can displaceair or gas that otherwise may resist and/or limit expansion of theexpandable bladder 343.

The expandable bladder 343 can be any suitable shape, size, and/orconfiguration. For example, in the embodiment shown in FIGS. 5 and 6,the expandable bladder 343 (e.g., flow controller) is a flexible bag,pouch, liner, and/or reservoir that includes and/or defines a singleopening to allow fluid flow from the fluid flow path 333 into theexpandable bladder 343. In some embodiments, the expansion of theexpandable bladder 343 (e.g., in response to the flow of bodily fluid)increases a volume of the expandable bladder 343 within thesequestration portion 334. As described above, the sequestration portion334 can include and/or can define a vent that can allow a flow of air orgas to be vented from a volume of the sequestration portion 334 that isoutside of and/or that surrounds the expandable bladder 343 as thevolume of the expandable bladder 343 is increased. In some embodiments,the outlet 336 and/or a portion of the fluid flow path 333 leading tothe outlet 336 is not vented and/or otherwise sealed and as such, theventing of the volume of the sequestration chamber 334 outside of theexpandable bladder 343 can facilitate and/or draw the flow of bodilyfluid into the expandable bladder 343. Although not shown in FIGS. 5 and6, in some embodiments, the expandable bladder 343 can include and/orcan house an expandable material such as a foam or sintered plastic,which can absorb, attract, urge, draw, retain, expand, and/or otherwiseinteract with at least a portion of the bodily fluid. Moreover, as thematerial expands in response to being wetted by the bodily fluid, theexpandable bladder 343 likewise expands allowing the bodily fluid toflow therein.

As described in detail above with reference to the devices 100 and/or200, the device 300 shown in FIGS. 5 and 6 can be used to divert (e.g.,passively) a first or initial volume of bodily fluid such thatsubsequently procured bodily fluid samples have reduced contaminationfrom microbes such as, for example, dermally residing microbes ormicrobes residing on incompletely sterilized transfer apparatus and/orthe like. For example, in some instances, a user such as a doctor,physician, nurse, phlebotomist, technician, etc. can manipulate thedevice 300 by inserting at least a portion of the needle 314 into apatient's vein (e.g., a venipuncture event) or into a reservoir ofcollected bodily fluid and/or can otherwise establish fluidcommunication between the needle 314 and the source of bodily fluid.Once in fluid communication with the patient, bodily fluid can flow fromthe bodily fluid source (e.g., the vein of the patient, or the collectedfluid source), through the inlet device 310, and into the housing 330.In some embodiments, the housing 330 can be in and/or can be placed in afirst or initial state in which an initial portion or volume of bodilyfluid can flow in or through at least a portion the fluid flow path 333and into the sequestration portion 334, and more particularly, into theexpandable bladder 343.

The initial portion and/or volume of bodily fluid can be any suitablevolume of bodily fluid, as described above. For example, in someinstances, the housing 330 can remain in the first state until apredetermined and/or desired volume (e.g., the initial volume) of bodilyfluid is transferred to the sequestration portion 334. In the embodimentshown in FIGS. 5 and 6, the initial volume can be associated with and/orat least partially based on an amount or volume of bodily fluid that canbe stored, contained, and/or sequestered in the expandable bladder 343.

After the initial volume of bodily fluid is transferred and/or divertedinto the sequestration portion 334 or expandable bladder 343, theinitial volume is sequestered, segregated, retained, contained,isolated, etc. in the sequestration portion 334. For example, in someembodiments, transferring the initial portion or volume of bodily fluidinto the expandable bladder 343 can place the expandable bladder 343 ina fully expanded state and/or configuration (e.g., a second state and/orconfiguration) and, as such, the volume of bodily fluid contained in theexpandable bladder 343 substantially prevents any subsequent volume ofbodily fluid from being disposed therein. In some embodiments, once theexpandable bladder 343 is fully expanded, a pressure differentialbetween the expanded bladder 343 and, for example, the fluid flow path333 can be reduced and/or substantially equalized such that nosubsequent volume of bodily fluid is “drawn” into the expanded bladder343. In other embodiments, the opening into the expandable bladder 343can include a valve, a selectively permeable membrane, fluid activated(e.g., bodily fluid activated) switch or seal, user activated switch orseal, and/or the like that can be transitioned from a first or openstate to a second or closed state to limit and/or substantially preventa flow of bodily fluid into or out of the expandable bladder 343. Asdescribed above, contaminants such as, for example, dermally residingmicrobes or the like dislodged during the venipuncture event, can beentrained and/or included in the initial volume of the bodily fluid andthus, can also be sequestered in the sequestration portion 334 (and/orexpandable bladder 343) when the initial volume is sequestered therein.

With the initial volume sequestered in the sequestration portion 334,the device 300 can transition to the second state in which a subsequentvolume(s) of bodily fluid can flow through at least a portion the fluidflow path 333 from the inlet 332 to the outlet 336. In the embodimentshown in FIGS. 5 and 6, the housing 330 is configured to automaticallytransition (e.g., without user intervention) from the first state to thesecond state once the initial volume of bodily fluid is sequestered inthe expandable bladder 343. Thus, as a subsequent flow and/or volume ofbodily fluid enters the fluid flow path 333, the housing 330 directsand/or diverts the flow through a portion of the fluid flow path 333 andto the outlet 336. As described in detail above, the outlet 336 is influid communication with one or more fluid collection devices (e.g., viathe flexible outlet tubing 347) such that the subsequent volume(s) ofthe bodily fluid can flow from the inlet 332, through the fluid flowpath 333, the outlet 336, and the flexible outlet tubing 347, and intothe fluid collection device (not shown). Thus, as described above,sequestering the initial volume of bodily fluid in the sequestrationportion 334 prior to collecting or procuring one or more sample volumesof bodily fluid reduces and/or substantially eliminates an amount ofcontaminants in the one or more sample volumes.

Moreover, in some embodiments, the arrangement of the expandable bladder343, an orifice or entrance into the expandable bladder 343, a valve,switch, or actuator disposed at in the orifice or entrance of theexpandable bladder 343, and/or the like can limit and/or substantiallyprevent an outflow of the bodily fluid from the expandable bladder inresponse to a negative pressure or the like produced by the fluidcollection device. In some embodiments, the vent and/or opening of thesequestration portion 334 can include a valve or flow controller thatwhen transitioned from an open or venting state to a closed or sealedstate, can result in a negative pressure within the volume of thesequestration portion 334 outside of the expandable bladder 343 operableto retain the initial volume of bodily fluid in the expandable bladder343. That is to say, the expandable bladder 343 is configured to retainand/or sequester the initial volume of bodily fluid despite at leastpartially being exposed to a negative pressure differential produced bythe fluid collection device. In other words, the expandable bladder 343can be a flow controller configured to selectively control a flow offluid into or out of the sequestration portion 334.

While the devices 200 and 300 are described herein as including thesequestration chambers 234 and 334, respectively, that are offset fromand/or non-coaxial with the inlets 232 and 332, respectively, in otherembodiments, a sequestration portion and/or at least a portion of asequestration portion can be “in-line” between an inlet and an outlet.For example, FIGS. 7 and 8 illustrate a fluid control device 400according to an embodiment. As described above with reference to thedevices 100, 200, and/or 300, the fluid control device 400 (alsoreferred to herein as “control device” or “device”) is configured towithdraw and sequester a first portion or amount (e.g., an initialamount) of bodily fluid from a patient such that any subsequentlywithdrawn amount, portion, and/or volume of bodily fluid issubstantially free of contaminants. In some embodiments, portions and/oraspects of the device 400 are substantially similar in form and/orfunction to the corresponding portions and/or aspects of the devices100, 200, and/or 300 described above. Accordingly, such similar portionsand/or aspects are not described in further detail herein.

As shown in FIG. 7, the control device 400 includes an inlet device 410and a housing 430 in fluid communication with and/or configured to beplaced in fluid communication with the inlet device 410. The inletdevice 410 can be any suitable device(s) such as, for example, an IVcatheter, a sharpened catheter or sharpened needle, a port, a coupler, aconnector, and/or any other suitable lumen-containing device. In theembodiment shown in FIGS. 7 and 8, the inlet device 410 is a butterflyneedle or other suitable access device having a body 411, a needle 414,and a flexible tubing 420. Moreover, the inlet device 410 is similar toand/or substantially the same as the inlet device 210 described indetail above with reference to FIGS. 2-4. Thus, the inlet device 410 isnot described in further detail herein. As described above withreference to the inlet devices 210 and 310 of the control devices 100and 200, while illustrated as a needle for procuring fluids directlyfrom a patient (e.g., from a vasculature of the patient) in FIGS. 7-8,the inlet device 410 can in other embodiments be configured to obtainfluid from a reservoir or container or the like of bodily fluidcollected from a patient. The inlet device in some instances can includesuitable ports or couplers or the like that can be connected tocorresponding ports or couplers or the like of a reservoir containingcollected bodily fluid or to corresponding ports or couplers of transferapparatus that may in turn be connected a collected source of bodilyfluid. In some embodiments, the inlet device to couple with a transferapparatus or a reservoir of collected fluid, can include associatedstructures and/or control devices to operate the inlet device to controlthe fluidic communication between the inlet device and the source ofbodily fluid.

The housing 430 includes a body 431 having an inlet 432 and an outlet436. In addition, the housing 430 defines a fluid flow path 433 and asequestration and/or diversion portion 434 (also referred to herein as“sequestration portion”). The body 431 of the housing 430 can be anysuitable shape, size, and/or configuration. For example, in someembodiments, the body 431 can be formed of a relatively rigid materialsuch as a plastic or the like and can be configured to retain its shapeand/or form when exposed to changes in pressure and/or inlet and outletflows of fluid. As shown in FIGS. 7 and 8, the inlet 432 formed by thebody 431 is physically coupled to an end portion of the flexible tubing420 and fluidically coupled to the inlet device 410 via a lumen 421defined by the flexible tubing 420 (e.g., the flexible tubing 420 is aflexible inlet tubing for the housing 430). Likewise, the outlet 436formed by the body 431 is physically and fluidically coupled to anoutlet tubing 447 (e.g., flexible medical tubing, and/or any othersuitable port or conduit) that defines a lumen 448 configured to placethe outlet in fluid communication with a fluid collection device (notshown). The fluid flow path 433 extends through the inlet 432 and placesthe inlet 432 in fluid communication with at least the sequestrationportion 434. Accordingly, the housing 430 can be similar in at leastform or function to the housing 230 and/or 330 described in detail abovewith reference to FIGS. 2-4 and 5-6, respectively. Thus, portions and/oraspects of the housing 430 are not described in further detail herein.

The housing 430 can differ from the portions 230 and 330, however, inthe arrangement of the sequestration portion 434. For example, while thesequestration portion 234 and the outlet 236 of the housing 230 wereoffset and/or non-coaxial from the inlet 232 thereof, in the embodimentshown in FIGS. 7 and 8, the sequestration portion 434 is “in-line” orcoaxial with the inlet 432 and the outlet 436. In other words, bodilyfluid can flow within the fluid flow path 433 of the housing 430 fromthe inlet 432 to or through the sequestration portion 434 and then canflow within the fluid flow path 433 from the sequestration portion 434to the outlet 436. In some embodiments, such an arrangement can forcecompliance with a diversion protocol or the like in which an initialvolume of bodily fluid is transferred or drawn into the sequestrationportion 434 prior to being transferred to the outlet 436, as describedin further detail herein. While the sequestration portion 434 isdescribed as being “in-line” or coaxial with the inlet 432 and theoutlet 436, in other embodiments, the fluid flow path 433 can bend orcurve such that the sequestration portion 434 is non-coaxial with theinlet 432 and/or the outlet 436 while remaining “in-line.”

As shown in FIG. 8, the sequestration portion 434 includes a flowcontroller or the like such as, for example, a hydrophilic material 440disposed therein. In some embodiments, the hydrophilic material 440 canbe substantially similar to and/or the same as the hydrophilic material240 described above with reference to FIGS. 2-4. In other embodiments,the hydrophilic material 440 can be any suitable material and/or flowcontroller configured to attract, collect, and/or absorb fluid. In theembodiment shown in FIGS. 7 and 8, the hydrophilic material 440 caninclude and/or can define a lumen 441 extending through the material440. For example, as shown in FIG. 8, the lumen 441 of the hydrophilicmaterial 440 extends through the entirety of the material 440. While thelumen 441 of the hydrophilic material 440 is shown as beingsubstantially straight, linear, and/or otherwise extending along asingle axis, in other embodiments, the lumen 441 of the hydrophilicmaterial 440 can be bent, curved, tortuous, and/or the like. In someembodiments, such a configuration of the lumen 441 may limit and/orsubstantially prevent a flow of bodily fluid from passing through thelumen 441 without contacting the hydrophilic material 440.

In some embodiments, the arrangement of the hydrophilic material 440 issuch that the lumen 441 is substantially closed and/or otherwise has arelatively small diameter prior to fluid contacting the hydrophilicmaterial 440 (e.g., when the hydrophilic material 440 is substantiallydry such as, prior to using the device 400). In some embodiments, theinitial diameter of the lumen 441 when in the closed configuration orstate can limit and/or can substantially prevent fluid from passingthrough the hydrophilic material 440. As fluid is placed in contact withthe hydrophilic material 440 disposed in the sequestration portion 434,the hydrophilic material 440 is configured to absorb at least a portionof the fluid and as a result, the hydrophilic material 440 expandsand/or swells. The expansion or swelling of the hydrophilic material 440can result in a similar and/or corresponding expansion or increase inthe diameter of the lumen 441 passing through the hydrophilic material440, which in turn, can allow a flow of the fluid through the lumen 441,as described in further detail herein.

As described in detail above with reference to the devices 100, 200,and/or 300, the device 400 shown in FIGS. 7 and 8 can be used to divert(e.g., passively) a first or initial volume of bodily fluid such thatsubsequently procured bodily fluid samples have reduced contaminationfrom microbes such as, for example, dermally residing microbes and/orthe like. For example, in some instances, a user such as a doctor,physician, nurse, phlebotomist, technician, etc. can manipulate thedevice 400 by inserting at least a portion of the needle 414 into apatient's vein (e.g., a venipuncture event) and/or can otherwiseestablish fluid communication between the needle 414 and the patient.Once in fluid communication with the patient, bodily fluid can flow fromthe bodily fluid source (e.g., the vein of the patient), through theinlet device 410, and into the housing 430.

In some embodiments, the housing 430 can be in a first or initial stateprior to use in which the hydrophilic material 440 is in an initial orfirst state or configuration (e.g., the hydrophilic material 440 issubstantially dry, as described above). As such, the bodily fluid canflow from the inlet 432, through a portion of the fluid flow path 433and into the sequestration portion 434, where the bodily fluid contactsthe hydrophilic material 440. A first amount or initial amount of bodilyfluid can be absorbed by the hydrophilic material 440, which results inan expansion or swelling of the material 440. In some embodiments, thefirst or initial amount of bodily fluid is a volume sufficient to wet orsaturate the hydrophilic material 440 to an extent that the lumen 441defined by the material 440 is transitioned to an open configuration orstate. That is to say, the expansion or swelling of the hydrophilicmaterial 440 increases the diameter of the lumen 441 passingtherethrough. Thus, any flow, amount, or volume of bodily fluid flowingthrough the fluid flow path 433 subsequent to the initial amount orvolume can flow through the lumen 441 having the increased diameter.

In some embodiments, the arrangement of the hydrophilic material 440and/or the sequestration portion 434 can be such that the bodily fluidis drawn into the sequestration portion in response to a pressuredifferential between, for example, the bodily fluid source (e.g., thepatient's blood stream) and the sequestration portion 434. In suchembodiments, the pressure differential can be sufficient to draw or urgethe bodily fluid to flow toward or into the hydrophilic material 440. Inaddition to or alternatively, in some embodiments, a fluid collectiondevice can be fluidically coupled to the outlet tubing 447 prior towithdrawing the initial volume of bodily fluid. In such instances, thefluid collection device can define a negative pressure (e.g., the fluidcollection device can be an evacuated container or the like) that can beoperable in drawing or withdrawing the bodily fluid from the patient. Insuch embodiments, because the sequestration portion 434 is upstream ofthe fluid collection device, the bodily fluid flowing through the fluidflow path 433 can enter the sequestration portion 434 and can engage thehydrophilic material 440, which in turn, absorbs, attracts, retains,and/or sequesters the initial volume of bodily fluid as the initialvolume flows into the sequestration portion 434. In other words, such anarrangement can increase a pressure differential between the bodilyfluid source (e.g., the patient's blood pressure or a container ofcollected bodily fluid or the like) and the sequestration portion 434that may otherwise be insufficient to transfer a desired volume ofbodily fluid into the sequestration portion 434 (e.g., as withvasculature of very sick, young, or elderly patients or from smallcollections of bodily fluid that do not exert much pressure).

The arrangement of the sequestration portion 434 and the hydrophilicmaterial 440 is such that the hydrophilic material 440 absorbs, retains,and/or sequesters the initial volume or amount of bodily fluid. Asdescribed in detail above, contaminants such as, for example, dermallyresiding microbes or the like dislodged during the venipuncture event(and/or other undesirable microbes), can be entrained and/or included inthe initial volume of the bodily fluid and thus, can also be sequesteredin or by the hydrophilic material 440 in the sequestration portion 434.In some embodiments, the saturation of the hydrophilic material 440(e.g., the absorption and/or sequestration of the initial amount orvolume) can place the device 400 in a second state or configuration, inwhich any subsequent volume of bodily fluid flows through the lumen 441of the hydrophilic material 440 (e.g., as a result of the increase indiameter thereof) and to the outlet 436 of the housing 430. As describedin detail above, the outlet 436 is in fluid communication with one ormore fluid collection devices (e.g., via the outlet tubing 447) suchthat the subsequent volume(s) of the bodily fluid can flow from theinlet 432, through the fluid flow path 433, the lumen 441 of thehydrophilic material 440, the outlet 436, and the outlet tubing 447, andinto the fluid collection device (not shown). Thus, as described above,sequestering the initial amount or volume of bodily fluid in thesequestration portion 434 (or in or by the hydrophilic material 440 orother flow controller disposed therein) prior to collecting or procuringone or more sample volumes of bodily fluid reduces and/or substantiallyeliminates an amount of contaminants in the one or more sample volumes.

While the devices 200, 300, and 400 are described herein as includingthe flexible tubing 220, 320, and 420, respectively, configured to placethe inlet devices 210, 310, and 410 in fluid communication with thesequestration portions 230, 330, and 430, respectively, in otherembodiments, a control device can include an inlet device and diverterand/or housing that are physically and/or fluidically coupled in anysuitable manner. For example, FIGS. 9-12 illustrate a fluid controldevice 500 according to an embodiment. As described above with referenceto the devices 100, 200, 300, and/or 400, the fluid control device 500(also referred to herein as “control device” or “device”) is configuredto withdraw and sequester a first portion or amount (e.g., an initialamount) of bodily fluid from a patient such that any subsequentlywithdrawn amount, portion, and/or volume of bodily fluid issubstantially free of contaminants. In some embodiments, portions and/oraspects of the device 500 are substantially similar in form and/orfunction to the corresponding portions and/or aspects of the devices100, 200, 300, and/or 400 described above. Accordingly, such similarportions and/or aspects are not described in further detail herein.

As shown in FIGS. 9 and 10, the control device 500 includes an inletdevice 510 and a housing 530 at least partially disposed within a body511 of the inlet device 510. The body 511 of the inlet device 510 can bea substantially hollow tube or body configured to receive at least aportion of the housing 530. While the inlet devices describedhereinabove have included a needle or the like, in the embodiment shownin FIGS. 9-12, a needle 514 is included in and/or coupled to a portionof the housing 530. As such, the housing 530 can be inserted into and/ordisposed within the inlet device 510 such that the needle 514 extendsthrough a distal opening defined by the body 511 of the inlet device510. In some embodiments, the arrangement of the inlet device 510 andthe housing 530 can facilitate use by maintaining a generally common orknown shape of the body of the inlet device 510 (e.g., similar to abutterfly needle or the like). In other embodiments, the body 511 of theinlet device 510 can be any suitable shape and/or size and need notresemble known devices or the like. As described previously withreference to inlet devices 210, 310, 410, while illustrated as beingconfigured for procuring fluids directly from a patient (e.g., from avasculature of the patient) in FIGS. 9-12, the inlet device 510 can inother embodiments be configured to obtain fluid from a reservoir orcontainer or the like of bodily fluid collected from a patient. Theinlet device in some instances can include suitable ports or couplers orthe like that can be connected to corresponding ports or couplers or thelike of a reservoir containing collected bodily fluid or tocorresponding ports or couplers of transfer apparatus that may in turnbe connected a collected source of bodily fluid. In some embodiments,the inlet device to couple with a transfer apparatus or a reservoir ofcollected fluid, can include associated structures and/or controldevices to operate the inlet device to control the fluidic communicationbetween the inlet device and the source of bodily fluid.

The housing 530 includes a body 531 that includes and/or forms an inlet532 and an outlet 536. In addition, the housing 530 defines a fluid flowpath 533 and a sequestration and/or diversion portion 534 (also referredto herein as “sequestration portion”). The body 531 of the housing 530can be any suitable shape, size, and/or configuration. For example, insome embodiments, the body 531 can be formed of a relatively rigidmaterial such as a plastic or the like and can be configured to retainits shape and/or form when exposed to changes in pressure and/or inletand outlet flows of fluid. The inlet 532 is physically and fluidicallycoupled to an end portion of the needle 514. More specifically, aproximal end portion of the needle 514 extends through the inlet 532 toplace a lumen 515 defined by the needle 514 in fluid communication withthe fluid flow path 533 defined by the housing 530. The outlet 536 isphysically and fluidically coupled to a flexible outlet tubing 547 (alsoreferred to herein as “outlet tubing”) configured to place the outlet influid communication with a fluid collection device (not shown).

As shown, for example, in FIG. 12, the outlet 536 is at least partiallydisposed within a slot 513 defined by the body 511 of the inlet device510. Accordingly, the outlet 536 can coupled to the outlet tubing 547without having to increase a size of the body 511 of the inlet device510. In some embodiments, the arrangement of the outlet 536 and/or aportion of the outlet tubing 547 extending through the slot 513, canallow the housing 530 to move within the body 511 of the inlet device510. In some such embodiments, the device 500 can be configured suchthat the housing 530 can be moved relative to the inlet device 511 toselectively position the needle 514 relative to the inlet device 510.For example, in some embodiments, the housing 530 can be in a proximalposition or the like prior to use such that the needle 514 is disposedwithin the inlet device 510. Similarly, after using the device 500 tocollect one or more bodily fluid samples, the housing 530 can be movedto and/or toward the proximal position (e.g., the pre-use position) toretract the used needle 514 into the inlet device 510. Accordingly, suchan arrangement can reduce undesired needle sticks or the like.

As shown in FIGS. 10 and 12, a portion of the body 531 of the housing530 includes and/or defines the sequestration portion 534. Morespecifically, the body 531 of the housing 530 can include and/or candefine the sequestration portion 534 at or in a portion that is proximalto the needle 514 and the outlet 536, as described in further detailherein. As described above with reference to the sequestration portion234 of the housing 230, the housing 530 and/or the sequestration portion534 includes and/or defines an opening 535 (e.g., a vent opening) influid communication with the sequestration portion 534 and/or otherwisehas a proximal end that is substantially open.

The sequestration portion 534 includes and/or houses one or more flowcontrollers configured to interact with the bodily fluid transferredinto the sequestration portion 534. For example, in the embodiment shownin FIGS. 9-12, the housing 530 includes a hydrophilic material 540 and avent material 542 (e.g., one or more flow controller), which can besimilar to and/or substantially the same as the hydrophilic material 240and the vent material 242, respectively, of the housing 230.Accordingly, when bodily fluid is transferred into the sequestrationportion 534, the hydrophilic material 540 can absorb, attract, retain,expand, and/or otherwise interact with at least a portion of the bodilyfluid, which in turn, can sequester and/or retain at least an initialportion of the bodily fluid within the sequestration portion 534, asdescribed in further detail herein.

The vent material 542 can be configured to vent the sequestrationportion 534 to allow, enhance, facilitate, and/or otherwise urge theflow of bodily fluid into the sequestration portion 534. The arrangementof the vent material 542 can be such that the bodily fluid wets the ventmaterial 542 as the bodily fluid is transferred into the sequestrationportion 534 and once sufficiently wetted and/or saturated, the ventmaterial 542 can transition from a configuration and/or state in whichthe vent material 542 vents the sequestration portion 534 to aconfiguration and/or state in which the vent material 542 seals thesequestration portion 534, as described above with reference to the ventmaterial 242. While the sequestration portion 534 is described above asincluding the vent material 542, in other embodiments, the sequestrationportion 534 can include a vent or opening including a selectivelypermeable valve, membrane, and/or the like, as described above withreference to the sequestration portion 234.

As described in detail above with reference to the devices 100, 200,300, and/or 400, the device 500 shown in FIGS. 9-12 can be used todivert (e.g., passively) a first or initial volume of bodily fluid suchthat subsequently procured bodily fluid samples have reducedcontamination from microbes such as, for example, dermally residingmicrobes or microbes residing on incompletely sterilized transferapparatus and/or the like. For example, in some instances, a user suchas a doctor, physician, nurse, phlebotomist, technician, etc. canmanipulate the device 500 by inserting at least a portion of the needle514 into a patient's vein (e.g., a venipuncture event) or a collectedsource of bodily fluid and/or can otherwise establish fluidcommunication between the needle 514 and the source of bodily fluid.Once in fluid communication with the source of bodily fluid, the fluidcan flow from the bodily fluid source (e.g., the vein of the patient),through the lumen 515 of the needle 514, and into the inlet 532 of thehousing 530.

In some embodiments, the housing 530 can be in a first or initial stateprior to use in which the hydrophilic material 540 is in an initial orfirst state or configuration (e.g., the hydrophilic material 540 issubstantially dry, as described above). As such, the bodily fluid canflow from the lumen 515 of the needle 514, through a portion of thefluid flow path 533 (e.g., a portion of the fluid flow path 533 that isproximal to the outlet 536, see e.g., FIG. 12), and into thesequestration portion 534. As described in detail above with referenceto the housing 230, a first amount or initial amount of bodily fluid canbe absorbed by the hydrophilic material 540, which results in anexpansion or swelling of the material 540. In some embodiments, thefirst or initial amount of bodily fluid is a volume sufficient to wet orsaturate the hydrophilic material 540 to, for example, a maximum levelor extent. Moreover, in some instances, the vent material 542 can bewetted or saturated substantially concurrently with the hydrophilicmaterial 540. In other embodiments, the vent material 542 can be wettedand/or saturated substantially after the hydrophilic material 540 issaturated. In some embodiments, the first or initial amount of bodilyfluid can be a volume of bodily fluid sufficient to fully wet and/orsaturate each of the hydrophilic material 540 and the vent material 542.In other words, the first or initial amount of bodily fluid can be avolume of bodily fluid sufficient to transition one or more flowcontroller from a first state to a second state.

After the initial volume of bodily fluid is transferred and/or divertedinto the sequestration portion 534, the initial volume is sequestered,segregated, retained, contained, isolated, etc. in the sequestrationportion 534. For example, in some instances, transferring the initialvolume of bodily fluid to the sequestration portion fully saturates thehydrophilic material 540 (and/or the vent material 542) such thatfurther absorption and/or retention of bodily fluid is limited and/orsubstantially prevented. Accordingly, the hydrophilic material 540sequesters the initial volume in the sequestration portion 534 andrejects any subsequent volumes of bodily fluid. As described above,contaminants such as, for example, dermally residing microbes or thelike dislodged during the venipuncture event, can be entrained and/orincluded in the initial volume of the bodily fluid and thus, can also besequestered in the sequestration portion 534 when the initial volume issequestered therein.

In some embodiments, transferring and/or sequestering the initial volumeof bodily fluid can automatically transition the device 500 from thefirst state to the second state in which a subsequent volume(s) ofbodily fluid can flow through at least a portion the fluid flow path 533to the outlet 536. For example, bodily fluid can flow through the lumen515 of the needle 514 and into the fluid flow path 533 of the body 531.Because the initial volume of bodily fluid is sequestered in thesequestration portion 534, the bodily fluid can flow, for example, in adistal direction toward and into the outlet 536 (see e.g., FIG. 12). Inother words, with the housing 530 in the second state or configuration,a subsequent flow and/or volume of bodily fluid can enter the fluid flowpath 533 and the housing 530 can direct and/or divert the flow through aportion of the fluid flow path 533 and into the outlet 536. As describedin detail above, the outlet 536 is in fluid communication with one ormore fluid collection devices (e.g., via the outlet tubing 547) suchthat the subsequent volume(s) of the bodily fluid can flow from theoutlet 536 and the outlet tubing 547, and into the fluid collectiondevice (not shown). Thus, as described above, sequestering the initialamount or volume of bodily fluid in the sequestration portion 534 (or inor by the hydrophilic material 540 disposed therein) prior to collectingor procuring one or more sample volumes of bodily fluid reduces and/orsubstantially eliminates an amount of contaminants in the one or moresample volumes.

While the device 500 is described above as including the sequestrationportion 534 that is static and/or in a fixed position proximal to theoutlet 536, in other embodiments, a diverter and/or housing can includean expandable and/or movable sequestration portion (or portion thereof).For example, FIGS. 13-16B illustrate a fluid control device 600according to an embodiment. As described above with reference to thecontrol devices 100, 200, 300, 400, and/or 500, the fluid control device600 (also referred to herein as “control device” or “device”) isconfigured to withdraw and sequester a first portion or amount (e.g., aninitial amount) of bodily fluid from a patient such that anysubsequently withdrawn amount, portion, and/or volume of bodily fluid issubstantially free of contaminants. In some embodiments, portions and/oraspects of the device 600 are substantially similar in form and/orfunction to the corresponding portions and/or aspects of the devices100, 200, 300, 400, and/or 500 described above. Accordingly, suchsimilar portions and/or aspects are not described in further detailherein.

As shown in FIGS. 13 and 14, the device 600 includes an inlet device 610and a housing 630 at least partially disposed within a body 611 of theinlet device 610. The body 611 of the inlet device 610 can be asubstantially hollow tube or body configured to receive at least aportion of the body of the housing 630. In the embodiment shown in FIGS.13-16B, the inlet device 610 is substantially similar in form and/orfunction to the inlet device 510 described above with reference to FIGS.9-12 and thus, is not described in further detail herein. It should benoted, however, that the inlet device 610 is presented by way of exampleand not limitation. The inlet device 610 can be any suitable inletdevice such as those described herein and can be configured to obtainfluid from any suitable bodily fluid source. For example, an inletdevice, in some instances, can include suitable ports or couplers or thelike that can be connected to corresponding ports or couplers or thelike of a reservoir containing collected bodily fluid or tocorresponding ports or couplers of transfer apparatus that may in turnbe connected a collected source of bodily fluid.

The housing 630 has a body 631 that includes and/or forms an inlet 632and an outlet 636. In addition, the housing 630 defines a fluid flowpath 633 and a sequestration and/or diversion portion 634 (also referredto herein as “sequestration portion”). The body 631 of the housing 630can be any suitable shape, size, and/or configuration. For example, insome embodiments, the body 631 can be formed of a relatively rigidmaterial such as a plastic or the like and can be configured to retainits shape and/or form when exposed to changes in pressure and/or inletand outlet flows of fluid. The inlet 632 is physically and fluidicallycoupled to an end portion of a needle 614. More specifically, a proximalend portion of the needle 614 extends through the inlet 632 to place alumen 635 defined by the needle 614 in fluid communication with thefluid flow path 633 defined by the housing 630. The outlet 636 isphysically and fluidically coupled to a flexible outlet tubing 647 (alsoreferred to herein as “outlet tubing”) configured to place the outlet influid communication with a fluid collection device (not shown). Asshown, for example, in FIGS. 16A and 16B, the outlet 636 is at leastpartially disposed within a slot 613 defined by the body 611 of theinlet device 610. In some embodiments, such an arrangement can allow formovement of the housing 630 relative to the inlet device 610, asdescribed in detail above with reference to the device 500.

The sequestration portion 634 includes and/or houses one or morematerials configured to interact with the bodily fluid transferred intothe sequestration portion 634. For example, in the embodiment shown inFIGS. 13-16B, the housing 630 includes a hydrophilic material 640 and avent material 642, that can each act as flow a flow controller, whichcan be similar to and/or substantially the same as the hydrophilicmaterial 540 and the vent material 542, respectively, of the housing530. Accordingly, when bodily fluid is transferred into thesequestration portion 634, the hydrophilic material 640 can absorb,attract, urge, retain, expand, and/or otherwise interact with at least aportion of the bodily fluid, which in turn, can sequester and/or retainat least an initial portion of the bodily fluid within the sequestrationportion 634, as described in further detail herein. In addition, as thebodily fluid is transferred into the sequestration portion 634, the ventmaterial 642 is wetted and/or saturated, which in turn, can transitionthe vent material 642 from a configuration and/or state in which thevent material 642 vents the sequestration portion 634 to a configurationand/or state in which the vent material 642 seals the sequestrationportion 634, as described above with reference to the vent material 542.Accordingly, at least a portion of the housing 630 can be substantiallysimilar in form and/or function to the housing 530 described above withreference to FIGS. 9-12.

The housing 630 can differ from the housing 530, however, by including amovable seal 644 configured to form a boundary and/or surface of thesequestration portion 634. For example, in the embodiment shown in FIGS.13-16B, the movable seal 644 includes and/or forms a sleeve 645 and anextension 646 extending from the sleeve 645. The seal 644 is movablydisposed in the inner volume of the body 631 and is in contact with aninner surface of the body 631 that defines at least a portion of thesequestration portion 634. More specifically, as shown in FIGS. 16A and16B, the sleeve 645 can be disposed about a portion of the hydrophilicmaterial 640 such that the sleeve 645 is disposed between the portion ofthe hydrophilic material 640 and the inner surface of the body 631. Insome embodiments, the hydrophilic material 640 and the seal 660 aremonolithically and/or unitarily formed. In other embodiments, thehydrophilic material 640 can be at least partially disposed within aportion of the seal 660 and retained therein via a press fit, frictionfit, and/or the like. In some embodiments, the seal 644, the hydrophilicmaterial 640, and the vent material 640 can collectively form a flowcontroller or the like that can selectively control a flow of fluidthrough the sequestration portion 634, as described in further detailherein.

The contact between the sleeve 645 of the seal 644 and the inner surfaceforms and/or defines a fluidic seal. In some embodiments, the seal 644can be formed from a material that is liquid impermeable while remaininggas permeable. In such embodiments, the seal 644 can prevent a flow ofbodily fluid to a position within the body 631 of the housing 630 thatis proximal to the seal 644 while allowing a flow of gas (e.g., air) topass through the seal 644. Accordingly, the vent material 642 can act tovent the sequestration portion 634 through the opening 635, as describedabove. In other embodiments, the seal 644 can be fluidically impermeable(e.g., impermeable to liquids and gases). In such embodiments, the ventmaterial 642 can be configured to vent a portion of the inner volume ofthe body 631 that is proximal to the seal 644. For example, in someinstances, the vent material 642 can vent air from the portion of theinner volume of the body 631 in response to movement of the fluidicallyimpermeable seal 644 in the proximal direction.

As shown in FIGS. 16A and 16B, the extension 646 of the seal 644 isconfigured to selectively obstruct the outlet 636 of the housing 630.For example, in some embodiments, the extension 646 can contact aportion of the inner surface of the body 631 to form and/or define afluidic seal therebetween. Thus, when the movable seal 644 is in adistal position (e.g., a first or initial position, state, and/orconfiguration), the extension 646 obstructs the outlet 636 andsequesters or isolates the outlet 636 from the fluid flow path 633.Conversely, when the seal 644 is moved to and/or placed in a proximalposition (e.g., a second or subsequent position, state, and/orconfiguration), the extension 646 is proximal to the outlet 636 suchthat the outlet 636 is in fluid communication with the fluid flow path633, as described in further detail herein.

As described in detail above with reference to the device 500 (or any ofthe other devices described herein), the device 600 shown in FIGS.13-16B can be used to divert (e.g., passively) a first or initial volumeof bodily fluid such that subsequently procured bodily fluid sampleshave reduced contamination from microbes such as, for example, dermallyresiding microbes and/or the like. For example, in some instances, auser such as a doctor, physician, nurse, phlebotomist, technician, etc.can manipulate the device 600 by inserting at least a portion of theneedle 614 into a patient's vein (e.g., a venipuncture event) and/or canotherwise establish fluid communication between the needle 614 and thepatient. Once in fluid communication with the patient, bodily fluid canflow from the bodily fluid source (e.g., the vein of the patient),through the lumen 635 of the needle 614, and into the inlet 632 of thehousing 630.

In some embodiments, the housing 630 can be in a first or initial stateprior to use in which the seal 644 is in the distal position, as shownin FIG. 16A. Moreover, with the housing 630 in the first or initialstate, the hydrophilic material 640 can be substantially dry,unsaturated, and/or otherwise unexpanded. As such, the bodily fluid canflow from the lumen 635 of the needle 614, through a portion of thefluid flow path 633, and into the sequestration portion 634, where thehydrophilic material 640 interacts with, attracts, draws, and/or absorbsthe bodily fluid. As described in detail above with reference to thehousing 230, a first amount or initial amount of bodily fluid can beabsorbed by the hydrophilic material 640 (and/or any other suitableexpandable or absorbent material), which results in an expansion orswelling of the material 640. In some embodiments, the first or initialamount of bodily fluid is a volume sufficient to wet or saturate thehydrophilic material 640 to, for example, a maximum level or extent.

In some embodiments, the expansion or swelling of the material 640 canresult in movement of the seal 644 in the distal direction, as indicatedby the arrow AA in FIG. 16B. In other words, as the hydrophilic material640 absorbs the first or initial amount of bodily fluid flowing into thefluid flow path 633, the material 640 can push or otherwise move theseal 644 in the distal direction. In some embodiments, the movement ofthe seal 644 can produce a negative pressure (e.g., as a result of anincrease in volume) within the sequestration portion 634 and/or thefluid flow path 633 that is operable to draw bodily fluid into thesequestration portion 634. As such, the hydrophilic material 640 and thenegative pressure can draw the first or initial amount or volume ofbodily fluid into the sequestration portion 634. Moreover, as describedabove, the vent material 642 can be configured to vent the housing 630and/or the sequestration portion 634 as the seal 644 is moved in the AAdirection.

After the initial volume of bodily fluid is transferred and/or divertedinto the sequestration portion 634, the initial volume is sequestered,segregated, retained, contained, isolated, etc. in the sequestrationportion 634. For example, in some instances, transferring the initialvolume of bodily fluid to the sequestration portion fully saturates thehydrophilic material 640 such that further absorption and/or retentionof bodily fluid is limited and/or substantially prevented. Accordingly,the hydrophilic material 640 sequesters the initial volume in thesequestration portion 634 and rejects any subsequent volumes of bodilyfluid. As described above, contaminants such as, for example, dermallyresiding microbes or the like dislodged during the venipuncture event,can be entrained and/or included in the initial volume of the bodilyfluid and thus, can also be sequestered in the sequestration portion 634when the initial volume is sequestered therein.

As described above, the movement of the seal 644 in the AA direction(e.g., the proximal direction) moves the extension 646 of the seal 644relative to the outlet 636. Specifically, as shown in FIG. 16B, movementof the seal 644 in response to the first or initial volume beingtransferred into the sequestration portion 634 and/or being absorbed bythe hydrophilic material 640, places the extension 646 in a proximalposition relative to the outlet 636. Thus, fluid communication isestablished between the outlet 636 and the fluid flow path 633, which inturn, is operable to transition the device 600 from the first state tothe second state in which a subsequent volume(s) of bodily fluid canflow through at least a portion the fluid flow path 633 and through theoutlet 636.

With the initial volume of bodily fluid is sequestered in thesequestration portion 634, the subsequent volume(s) of bodily fluid canflow through the lumen 635 of the needle 614, through a portion of thefluid flow path 633, and into the outlet 636. In other words, with thehousing 630 in the second state or configuration, a subsequent flowand/or volume of bodily fluid can enter the fluid flow path 633 and thehousing 630 can direct and/or divert the flow through a portion of thefluid flow path 633 and into the outlet 636. As described in detailabove, the outlet 636 is in fluid communication with one or more fluidcollection devices (e.g., via a lumen 648 defined by the outlet tubing647) such that the subsequent volume(s) of the bodily fluid can flowfrom the outlet 636 and the outlet tubing 647, and into the fluidcollection device (not shown). Thus, as described above, sequesteringthe initial amount or volume of bodily fluid in the sequestrationportion 634 (or in or by the hydrophilic material 640 disposed therein)prior to collecting or procuring one or more sample volumes of bodilyfluid reduces and/or substantially eliminates an amount of contaminantsin the one or more sample volumes.

While the sequestration portion 634 is described above as receiving theinitial volume of bodily fluid, which in turn, results in an expansionof the hydrophilic material 640 and the movement of the seal 644 in theAA direction (see e.g., FIG. 16 B), in other embodiments, the flow ofthe bodily fluid can produce and/or can be associated with a force thatis operable in transitioning the housing 630 from the first state to thesecond state. For example, in some embodiments, a force associated withthe flow of bodily fluid entering the sequestration portion 634 can besufficient to move the seal regardless of whether the hydrophilicmaterial 640 expands in response to contact with and/or absorption ofthe initial volume of bodily fluid. In other words, the flow of bodilyfluid can enable and/or can be operable to transition the housing 630and/or control device 600 from the first state to the second state. Insome embodiments, this can be based on a force associated with the flowof bodily fluid. In other embodiments, the bodily fluid can transition amember or membrane from a first state to a second state. For example, insome embodiments, the extension 646 of the seal 644 can include and/orcan be formed of a dissolvable material or the like. As such, the bodilyfluid can contact the dissolvable material, which, after a desired orpredetermined time can dissolve or otherwise transition from a firststate in which the material blocks the outlet 636 to a second state inwhich the material does not block the outlet 636 (e.g., is at leastpartially dissolved).

FIGS. 17-20 illustrate a fluid control device 700 according to anotherembodiment. As described above with reference to the devices 100, 200,300, 400, 500, and/or 600, the fluid control device 700 (also referredto herein as “control device” or “device”) is configured to withdraw andsequester a first portion or amount (e.g., an initial amount) of bodilyfluid from a patient such that any subsequently withdrawn amount,portion, and/or volume of bodily fluid is substantially free ofcontaminants. In some embodiments, portions and/or aspects of the device700 are substantially similar in form and/or function to thecorresponding portions and/or aspects of any of the devices describedabove. Accordingly, such similar portions and/or aspects are notdescribed in further detail herein.

As shown in FIG. 17, the control device 700 includes an inlet device 710and a housing 730 in fluid communication with and/or configured to beplaced in fluid communication with the inlet device 710. The inletdevice 710 can be any suitable device(s) such as, for example, an IVcatheter, a sharpened catheter or sharpened needle, and/or any othersuitable lumen-containing device. For example, in the embodiment shownin FIGS. 17-20, the inlet device 710 is a butterfly needle or othersuitable access device having a body 711, a needle 714, and a flexibletubing 720. Moreover, the inlet device 710 is similar to and/orsubstantially the same as the inlet device 210 described in detail abovewith reference to FIGS. 2-4. Thus, the inlet device 710 is not describedin further detail herein. As described previously with reference to theinlet devices 210, 310, 410, 510, and 610, while illustrated as beingconfigured for procuring fluids directly from a patient (e.g., from avasculature of the patient) in FIGS. 17-19, in other embodiments, theinlet device 710 can be configured to obtain bodily fluid from anysuitable bodily fluid source, reservoir, and/or container, as describedabove.

The housing 730 includes a body 731 having and/or forming an inlet 732,a first outlet 736, and a second outlet 737. In addition, the housing730 defines a fluid flow path 733 configured to selectively place theinlet 732 in fluid communication with the first outlet 736 or the secondoutlet 737 (see e.g., FIG. 20). The body 731 of the housing 730 can beany suitable shape, size, and/or configuration. For example, in theembodiment shown in FIGS. 17-20, the body 731 forms a T-connector orY-connector. In some embodiments, the body 731 can be formed of arelatively rigid material such as a plastic or the like and can beconfigured to retain its shape and/or form when exposed to changes inpressure and/or inlet and outlet flows of fluid.

As shown, the inlet 732 is coupled to the flexible tubing 720 (e.g., theflexible tubing 720 is a flexible inlet tubing for the housing 730),which defines a lumen configured to place the inlet 732 in fluidcommunication with the inlet device 710. The first outlet 736 is coupledto a first flexible outlet tubing 738 (also referred to herein as “firstoutlet tubing”), which defines a lumen 739 configured to receive a firstor initial volume of bodily fluid flowing through the housing 730. Thefirst outlet tubing 738 is also coupled to a vent 735 having a ventmaterial 742 that can selectively vent the lumen 739 of the first outlettubing 738. As such, at least a portion of the lumen 739 can form, forexample, a sequestration and/or diversion portion and/or the like, asdescribed in further detail herein. The second outlet is in fluidcommunication with a second flexible outlet tubing 747 (also referred toherein as “second outlet tubing”), which defines a lumen 748 configuredto place the second outlet 747 in fluid communication with one or morefluid collection devices (not shown).

The fluid flow path 733 defined by the housing 730 establishes selectivefluid communication with the first outlet 736 and the second outlet 737.As shown in FIGS. 19 and 20, the housing 730 is arranged such that thefluid flow path 733 restricts and/or reduces at or near the first outlet736 and the second outlet 737. In some embodiments, for example, aportion of the fluid flow path 733 associated with and/or defined by thefirst outlet 736 can be offset and/or misaligned from a portion of thefluid flow path 733 associated with and/or defined by the inlet 732,which in turn, forms and/or defines a reduced diameter and/or othersuitable restriction therebetween. Likewise, a portion of the fluid flowpath 733 associated with and/or defined by the second outlet 737 can beoffset and/or misaligned from the portion of the fluid flow path 733associated with and/or defined by the inlet 732, which in turn, formsand/or defines a reduced diameter and/or other suitable restrictiontherebetween. In some embodiments, the restrictions or the like canallow for selective fluid flow from the inlet 732 to the first outlet736 or the second outlet 737 based on, for example, a magnitude of apressure differential and/or the like, as described in further detailherein.

While the fluid flow path 733 is described above as forming arestriction or the like within the fluid flow path 733 to both the firstoutlet 736 and the second outlet 737, in other embodiments, the housing730 may define and/or include a restricted flow path for either thefirst outlet 736 or the second outlet 737. For example, in someembodiments, the housing 730 can form a flow restriction and/or the likewithin the fluid flow path 733 leading to the second outlet 737. In someembodiments, the flow restriction can restrict a fluid flow from theinlet 732 toward the second outlet 737, while there is no such flowrestriction in a flow of the fluid from the inlet 732 toward the firstoutlet 736. In some instances, such an arrangement can result in adesired and/or predetermined flow of bodily fluid through the firstoutlet 736 and into the first outlet tubing 738 (e.g., the sequestrationportion) prior to a flow of bodily fluid through the second outlet 737and toward the second outlet tubing 747.

As described in detail above with reference to the devices 100, 200,300, 400, 500, and/or 600, the device 700 shown in FIGS. 17-20 can beused to divert (e.g., passively) a first or initial volume of bodilyfluid such that subsequently procured bodily fluid samples have reducedcontamination from microbes such as, for example, dermally residingmicrobes and/or the like. For example, in some instances, a user such asa doctor, physician, nurse, phlebotomist, technician, etc. canmanipulate the device 700 by inserting at least a portion of the needle714 into a patient's vein (e.g., a venipuncture event) and/or canotherwise establish fluid communication between the needle 714 and thepatient. Once in fluid communication with the patient, bodily fluid canflow from the bodily fluid source (e.g., the vein of the patient),through the inlet device 710, and into the housing 730.

In some embodiments, the housing 730 can be in a first or initial stateprior to use and/or prior to establishing fluid communication betweenthe second outlet tubing 747 and one or more fluid collection devices(not shown). Although not shown, in such embodiments, the second outlettubing 747 can include a port or the like that can be in a closedconfiguration prior to coupling to the fluid collection device such thatthe second outlet tubing 747 is substantially sealed. Conversely, asdescribed above, the first outlet tubing 738 is coupled to the vent 735which can be configured to vent the lumen 739 of the first outlet tubing738 (e.g., a sequestration portion, reservoir, and/or chamber) when thehousing 730 is in the first or initial state. In this manner, a pressuredifferential (e.g., a negative pressure differential) between the lumen739 of the first outlet tubing 738 and, for example, the lumen 721 ofthe flexible tubing 720 can be greater than a pressure differentialbetween the lumen 748 of the second outlet tubing 747 and the lumen 721of the flexible tubing 720. Thus, as bodily fluid flows into the fluidflow path 733, the bodily fluid will flow into the first outlet 736 inresponse to the greater pressure differential (e.g., based at least inpart on the venting of the first outlet tubing 738). That is to say,when the housing 730 is in the first or initial state, the housing 730diverts and/or directs the flow of bodily fluid from the inlet 732 tothe first outlet 736. Moreover, in some embodiments, the housing 730 candefine and/or include one or more flow restrictions or the like betweenthe fluid flow path 733 and the second outlet 737, which can result in adesired and/or predetermined flow of bodily fluid from the fluid flowpath 733 and through the first outlet 736.

As such, the bodily fluid can flow from the inlet 732, through a portionof the fluid flow path 733 and the first outlet 736, and into the lumen739 of the first outlet tubing 738, as indicated by the arrow BB in FIG.20. A first amount or initial amount of bodily fluid can be transferredinto the lumen 739 of the first outlet tubing 738. In some instances,the first outlet tubing 738 can be bent, flexed, and/or positioned suchthat flow of the bodily fluid into the lumen 739 of the first outlettubing 738 is assisted and/or enhanced by gravitational forces. Forexample, in some instances, an end portion of the first flexible outlettubing 738 (e.g., the end portion coupled to and/or including the vent735) can be placed in a position below the body 731 of the housing 730(e.g., at a lower elevation), thereby facilitating the flow of bodilyfluid toward the vent 735.

In some instances, the first or initial amount of bodily fluid is avolume sufficient to wet or saturate the vent material 742. As describedabove with reference to the vent material 242 included in the housing230, the vent material 742 (e.g., flow controller) can be configured totransition from an open or venting state or configuration to a closed orsealed configuration in response to being wetted or saturated (e.g.,fully saturated). In this manner, transferring the first or initialvolume of bodily fluid into the lumen 739 of the first outlet tubing 738(e.g., the sequestration portion, flow path, lumen, chamber, etc.) sealsthe vent material 742, which in turn, allows the pressure within thelumen 739 to equalize and/or substantially equalize with, for example, apressure in the fluid flow path 733 and/or the lumen 721 of the flexibletubing 720. In some embodiments, the first or initial volume of bodilyfluid can be a volume sufficient to fully fill the lumen 739 of thefirst outlet tubing 738 with or without the vent material 742 becomingfully saturated. In such embodiments, the first outlet tubing 738 caninclude, for example, a valve or selectively permeable membraneconfigured to limit and/or substantially prevent an outflow of thebodily fluid from the first outlet tubing 738. In some embodiments, sucha valve or membrane can be automatically activated, user activated,and/or a combination thereof.

The arrangement of the first outlet tubing 738 (e.g., the sequestrationchamber) is such that the lumen retains and/or sequesters the initialvolume or amount of bodily fluid therein. As described in detail above,contaminants such as, for example, dermally residing microbes or thelike dislodged during the venipuncture event, can be entrained and/orincluded in the initial volume of the bodily fluid and thus, can also besequestered in the first outlet tubing 738. In some embodiments, fullyfilling the lumen 739 of the first outlet tubing 738 and/or saturatingthe vent material 742 can place the housing 730 and/or the device 700 ina second state or configuration, in which any subsequent volume ofbodily fluid flows through the fluid flow path 733 and into the secondoutlet 737, as indicated by the arrow CC in FIG. 20.

As described in detail above, the second outlet 737 is in fluidcommunication with one or more fluid collection devices (e.g., via thesecond outlet tubing 747) such that the subsequent volume(s) of thebodily fluid can flow from the inlet 732, through the fluid flow path733, the second outlet 736, and the second outlet tubing 747, and intothe fluid collection device (not shown). Thus, as described above,sequestering the initial amount or volume of bodily fluid in the firstoutlet tubing 738 (e.g., the sequestration chamber) prior to collectingor procuring one or more sample volumes of bodily fluid reduces and/orsubstantially eliminates an amount of contaminants in the one or moresample volumes.

FIGS. 21 and 22 illustrate a fluid control device 800 according toanother embodiment. As described above with reference to the controldevices 100, 200, 300, 400, 500, 600, and 700, the fluid control device800 can be configured to withdraw and sequester or isolate or retain afirst portion or amount (e.g., an initial amount) of bodily fluid from apatient or a reservoir of collected bodily fluid and subsequentlywithdraw a second portion or amount (e.g., a subsequent amount) ofbodily fluid for use, for example, in bodily fluid sampling and/ortesting. By sequestering the first portion or amount of bodily fluid,contaminants, or the like such as, for example, dermally residingmicrobes dislodged during venipuncture or microbes residing inincompletely sterilized transfer apparatus when transferring bodilyfluid samples are similarly sequestered, leaving the second portion oramount of bodily fluid substantially free of contaminants. In someembodiments, portions and/or aspects of the control device 800 aresubstantially similar in form and/or function to the correspondingportions and/or aspects of the control device 100 described above withreference to FIG. 1. Accordingly, such similar portions and/or aspectsare not described in further detail herein.

The control device 800 can be any suitable device or set of devicesconfigured to (1) receive a flow of bodily fluid, (2) store andsequester a first volume or initial volume of the bodily fluid, and (3)direct, divert, and/or otherwise facilitate a subsequent flow of thebodily fluid to a fluid collection device (not illustrated). In theembodiment illustrated in FIGS. 21 and 22, the control device 800includes an inlet 832 (or inlet portion) and an outlet 836 (or outletportion), and defines a sequestration and/or diversion portion 834 (alsoreferred to herein as “sequestration portion”). In addition, the controldevice 800 defines one or more fluid flow paths 813 between the inlet832 and the sequestration portion 834 and/or between the inlet 832 andthe outlet(s) 816, as described in further detail herein.

The inlet 832 of the control device 800 is configured to be fluidicallycoupled to an inlet device (not shown in FIGS. 21 and 22) to place thecontrol device 800 in fluid communication with a bodily fluid sourcesuch as, for example, the vasculature of a patient or any other suitablebodily fluid source. The inlet device can be any suitable device or setof devices. For example, in some embodiments, the inlet device can be anintravenous (IV) catheter, a needle, and/or any other suitablelumen-containing device. In other embodiments, the inlet device can be aport, a valve, and/or the like such as, for example, a Luer Lok® or anyother suitable coupler. In such embodiments, the inlet device (e.g.,port or coupler) can be configured to couple to an access device influid communication with a patient (e.g., a placed or indwelling IVcatheter or needle) and/or in fluid communication with any othersuitable bodily fluid source. In some embodiments, the inlet 832 can bephysically and fluidically coupled to the inlet device via a lock,coupler, port, etc. In other embodiments, the inlet 832 can be in fluidcommunication with the inlet device via an intermediate lumen-containingdevice such as, for example, sterile tubing or the like. In still otherembodiments, the inlet 832 of the control device 800 can form and/or canbe integrally or monolithically formed with the inlet device.Accordingly, the inlet 832 and/or inlet device can be any suitabledevice, component, and/or feature configured to obtain bodily fluid fromany suitable bodily fluid source such as those described above.

The control device 800 can be any suitable shape, size, and/orconfiguration. For example, in some embodiments, the control device 800can have a size that is at least partially based on a volume of bodilyfluid at least temporarily stored, for example, in the sequestrationportion 834. As shown in the cross-sectional view in FIG. 22, thecontrol device 800 can include and/or can form a bifurcation (e.g., aY-shaped or T-shaped bifurcation, or the like) forming one or moreportions of the fluid flow path 833. In some embodiments, the controldevice 800 can be formed of a relatively rigid material such as rigidplastic or the like and can be configured to retain its shape and/orform when exposed to changes in pressure and/or inlet and outlet flowsof fluid. In some embodiments, some portions of the control device 800(e.g., the sequestration portion 834) can be formed of a relativelyrigid material while some other portions of the control device 800(e.g., tubing or the like defining at least a portion of the flowpath(s) 833) can be formed of relatively flexible material such asflexible plastic, rubber, or the like.

In some embodiments, the control device 800 can be configured such thata first portion of the fluid flow path 833 (also referred to herein as“flow path”) places the inlet 832 in selective fluid communication withthe sequestration portion 834, and a second portion of the flow path 833places the inlet 832 in selective fluid communication with the outlet836. In some embodiments, the different portions of the flow path 833can be formed by integrally or monolithically constructed portions ofthe control device 800. In other embodiments, the portions of the flowpath 833 can be formed by assembly of one or more components of thecontrol device 800. For example, in some embodiments, the inlet 832 (orinlet portion) can include and/or can define a first portion of the flowpath 833, the sequestration portion 834 (or a portion of thesequestration portion 834) can include and/or can form a second portionof the flow path 833, and the outlet 836 (or outlet portion) can includeand/or can define a third portion of the flow path 833. In someembodiments, the inlet 832 (or inlet portion), the sequestration portion834 (or portion thereof), and the outlet 836 (or outlet portion) caninclude and/or can be formed with or by one or more tubes or otherlumen-containing devices, coupled to each other through one or moresuitable couplers or ports (e.g., a T-connector, Y-connector, and/or anyother suitable coupler(s)) or attached to each other through anysuitable mechanism to form portions of a continuous fluid flow path 833.More particularly, in some embodiments, the control device 800 caninclude a junction 817 or the like collectively formed at or near aconnection of the inlet 832 (or inlet portion), the sequestrationportion 834 (or portion thereof), and the outlet 836 (or outletportion). As described in further detail herein, in some embodiments,the control device 800 can be configured to transition at or near thejunction 817 to control a flow of bodily fluid therethrough.

The control device 800 (and/or the inlet 832, the sequestration portion834, the outlet 836, and/or the junction 817) can be arranged such thatany suitable portion of the flow path 833 has any suitable and/ordesired length, width, shape, and/or configuration. Similarly, anysuitable portion(s) of the flow path 833 can have any suitable formand/or can include any suitable inner surface (e.g., a textured innersurface, a grooved inner surface, a smooth inner surface, etc.). Forexample, in some embodiments, a portion of the flow path 833 formed byand/or formed between the inlet 832 and the sequestration portion 834(or portions thereof) can be configured to, for example, facilitatefluid flow towards the sequestration portion 834 (e.g., relative to theoutlet 836). For example, in some embodiments, such a portion of theflow path 833 can be relatively wider than a portion of the flow path833 defined between, for example, the junction 817 and the outlet 836.In other embodiments, the portion of the control device 800 defining theportion of the flow path 833 between the inlet 832 and the junction 817and/or the junction 817 and the sequestration portion 834 can have atextured inner surface (e.g., a pitted inner surface) configured tofacilitate absorption, attraction, and/or wicking of bodily fluid. Insome embodiments, the fluid flow path 833 can be a continuous fluid flowpath including one or more portions. In other embodiments, the controldevice 800 can be configured to selectively direct, divert, and/orcontrol flow of bodily fluid through the portions of the fluid flow path833 via an automatic actuator (e.g., not involving user intervention) ora user-controlled actuator or flow controller, such as a valve,membrane, and/or the like. For example, in some embodiments, thejunction 817 can include any suitable actuator (e.g., a passive actuatoror an active actuator).

The sequestration portion 834 of the control device 800 is at leasttemporarily placed in fluid communication with the inlet 832 via thefluid flow path 833 (e.g., defined at least in part by the inlet 832,the junction 817, and the sequestration portion 834. As described infurther detail herein, the sequestration portion 834 is configured to(1) receive a flow and/or volume of bodily fluid from the inlet 832, and(2) sequester (e.g., separate, segregate, contain, retain, isolate,etc.) the flow and/or volume of bodily fluid therein. The sequestrationportion 834 of the control device 800 can be formed integrally, as aportion of the control device 800. Alternatively, the sequestrationportion 834 can be formed separately and be configured to be attached orassembled onto the control device 800 though a suitable attachment orconnection mechanism or member (e.g., the junction 817). For example,the sequestration portion 834 can be made with an open end portion (notshown) configured to matingly connect with an open end portion of thecontrol device 800 which can be, for example, an open end portion of thejunction 817 that is integrally formed with the control device 800 orseparately formed and assembled onto the control device 800. The matingconnection can be through any suitable connection mechanism, member, orcoupler such as a pressure fitting, a friction fitting, a barb fitting,one or more locking couplers, etc.

The sequestration portion 834 can be any suitable shape, size, and/orconfiguration. In some embodiments, the control device 800 can include asequestration portion 834 having a specific shape, size, and/orconfiguration. For example in the embodiment shown in FIGS. 21 and 22,the sequestration portion 834 is at least partially formed by thecontrol device 800 and is configured to have a relatively flatcylindrical shape, indicated in the front view in FIG. 21 and in thecross sectional view in FIG. 22.

The sequestration portion 834 and/or a portion of the control device 800defining and/or forming the sequestration portion 834 further includesand/or defines an opening 835 (e.g., a vent, port, aperture, orifice, orthe like) in fluid communication with the sequestration portion 834. Asdescribed in detail above with reference to the sequestration portion134, the sequestration portion 834 can have any suitable volume and/orfluid capacity (e.g., from one or more drops of bodily fluid to 50 mL ormore of bodily fluid). In some embodiments, the volume or fluid capacitycan be defined by one or more portions of the control device 800 inaddition to the sequestration portion 834, for example, a portion of theflow path 833 and/or the junction 817. As such, transferring bodilyfluid into the sequestration portion 834 flushes at least a portion ofthe fluid flow path 833, which in turn, can remove, entrain, and/orsequester prior contaminants contained therein.

As shown in FIG. 22, the sequestration portion 834 can include and/orcan house one or more flow controllers configured to interact with thebodily fluid transferred into the sequestration portion 834. Forexample, in some embodiments, the sequestration portion 834 can includeone or more flow controllers including a material or group of materialsconfigured to interact with the bodily fluid. In such embodiments, theone or more materials can be any suitable configuration such as theconfiguration described above with reference to the sequestrationportion 134. For example, in the embodiment shown in FIGS. 21 and 22,the sequestration portion 834 of the control device 800 includes ahydrophilic material 840 (e.g., foam, sintered plastic,bodily-fluid-absorbent material, and/or the like) disposed within thesequestration portion 834. The sequestration portion 834 also includes avent material 842 (e.g., semi-permeable membrane or material, etc.)disposed within the opening 835. Accordingly, when bodily fluid istransferred into the sequestration portion 834, the hydrophilic material840 can absorb, attract, urge, draw, retain, and/or otherwise interactwith at least a portion of the bodily fluid, which in turn, can expandor swell, and sequester and/or retain at least an initial portion of thebodily fluid within the sequestration portion 834, as described infurther detail herein. In other words, the hydrophilic material 840 canenhance and/or facilitate wicking, which in turn, can draw bodily fluidinto the sequestration portion 834 (e.g., the hydrophilic material 840can at least partially control a flow of fluid into or out of thesequestration portion 834). The hydrophilic material 840 can assume anyshape or size when disposed within the sequestration portion 834. Forexample, in some embodiments, the hydrophilic material 840 can assume arelatively flat and/or thin cylindrical shape disposed within acylindrical sequestration portion 834, as shown in FIGS. 21 and 22.

In some embodiments, the hydrophilic material 840 disposed in thesequestration portion 834 can be configured to occupy a first portion ofthe volume of the sequestration portion 834 and leave unoccupied asecond portion of the sequestration portion 834. That is, thehydrophilic material 840 can be configured to have a pre-specified sizeand/or shape prior to use such that when disposed within thesequestration portion 834 there remains a volume, space, or gap withinthe sequestration portion 834 that is not occupied by the hydrophilicmaterial 840. For example, as shown in FIG. 22, the hydrophilic material840 is disposed in the sequestration portion 834 such that a space 845(e.g., a gap, volume, and/or otherwise unoccupied portion) is definedbetween a surface of the hydrophilic material 840 and an inner surfaceof the sequestration portion 834. Moreover, the space 845 is in fluidiccommunication with the portion of the flow path 833 that extendsbetween, for example, the junction 817 and the sequestration portion834.

In some embodiments, the space 845 can include, for example, a volume ofair or other gaseous contents that can be vented through the opening 835prior to drawing in bodily fluid to be sequestered. In some embodiments,the space 845 can be configured to at least accommodate any expansion ofthe hydrophilic material 840 upon absorption of the initial volume ofbodily fluid. In some embodiments, the space 845 can be configured tofacilitate and/or otherwise allow expansion of the hydrophilic material840, which in turn, can result in a pressure differential that draws orhelps draw a flow of bodily fluid towards and into the sequestrationportion 834. For example, the negative pressure differential can beproduced between the sequestration portion 834 and the junction 817, aportion of flow path 833, and/or the inlet 832 that is sufficient tourge or draw the initial volume of bodily fluid to flow from the inlet832, through the junction 817, and toward and/or into the sequestrationportion 834. In other embodiments, the space 845 can be relatively smallto reduce an amount of air or other gaseous content disposed thereinthat otherwise is vented, while still allowing for expansion of thehydrophilic material 840.

The vent material 842 can be configured to vent the sequestrationportion 834 via the opening 835 to allow, enhance, facilitate, and/orotherwise urge or draw the flow of bodily fluid into the sequestrationportion 834. The vent material 842 can also serve to keep the initialvolume of bodily fluid transferred into the sequestration portion 834disposed or sequestered therein. The arrangement of the vent material842 can be such that the bodily fluid wets the vent material 842 as thebodily fluid is transferred into the sequestration portion 834. Inresponse to the wetting, the vent material 842 can swell and/or canotherwise can transition from a configuration and/or state in which thevent material 842 vents the sequestration portion 834 to a configurationand/or state in which the vent material 842 seals the sequestrationportion 834. That is to say, the vent material 842 can be a self-sealingmaterial configured to selectively allow a flow of gas (e.g., air) tovent from the sequestration portion 834 through the opening 835 until itis saturated with a liquid (e.g., bodily fluid), thereby sealing theopening 835.

In some instances, the wetting or transitioning of the vent material 842is associated with and/or correlates to an amount or volume of bodilyfluid transferred to the sequestration portion 834. For example, in someembodiments, the vent material 842 can be placed in and/or cantransition to a sealed configuration or state when a predeterminedand/or desired volume of bodily fluid is transferred into thesequestration portion 834 (e.g., the initial portion or initial volume).In some embodiments, the sequestration portion 834 can sequester and/orretain the predetermined and/or desired volume of bodily fluid in thesequestration portion 834 in response to the vent material 842transitioning to the sealed configuration, Moreover, when the ventmaterial 842 is in the sealed state and/or when the initial portion ofbodily fluid is transferred to the sequestration portion 834, thecontrol device 800 can transition (e.g., passively and/or automatically,without user intervention) from the first state to a second state, inwhich bodily fluid can flow, for example, from the inlet 832, throughthe junction 817, and to, towards, or through the outlet 836.

Both the hydrophilic material 840 and the vent material 842 can be anysuitable shape, size, and/or configuration. In some embodiments, thehydrophilic material 840 and the vent material 842 can be substantiallysimilar to the hydrophilic or wicking material and the selectivelypermeable member or membrane, respectively, described above withreference to the sequestration portion 134 shown in FIG. 1. While thehydrophilic material 840 and the vent material 842 are shown anddescribed herein as being separate components and/or members, in someembodiments, a control device and/or a sequestration chamber can includea single piece of hydrophilic material that can form and/or can act asthe hydrophilic material 840 and the vent material 842. In otherembodiments, the hydrophilic material 840 and the vent material 842 canbe coupled during manufacturing and/or otherwise co-formed or unitarilyformed. Accordingly, the hydrophilic material 840 and the vent material842 each can be a flow controller or can collectively be a flowcontroller configured to selectively control a flow of fluid (e.g., gasand/or liquid) into and out of the sequestration portion 834.

The outlet 836 formed by and/or included in the control device 800 is atleast fluidically coupled to the junction 817 and/or is otherwise incoupled to the control device 800 such that the outlet 836 is in fluidcommunication with the flow path 833. For example, in some embodiments,the outlet 836 can be physically and fluidically coupled to the junction817 and/or otherwise can be an integrally formed portion of the controldevice 800. In some other embodiments, the control device 800, thejunction 817, and/or the outlet 836 (or outlet portion) can include asterile flexible tubing or the like configured to place the outlet 836in fluid communication with the junction 817 and thus, in fluidcommunication with and/or defining at least a portion of the flow path833. Although described as a single tubing, the outlet 836 can be influid communication with and/or coupled to, for example, the junction817 via one or more pieces of tubing, which can be joined together toform a continuous lumen.

Although not specifically shown in FIGS. 21 and 22, the outlet 836 canbe any suitable outlet, opening, port, lock, seal, coupler, etc. and isin fluid communication with at least a portion of the fluid flow path833. For example, the outlet 836 can be a port, coupler, transferadapter, and/or device that is coupled to control device 800 (e.g., viaa flexible outlet tubing or the like) via any suitable connection, fit,adhesive, etc. In some embodiments, the outlet 836 can include and/orcan be coupled to an outlet needle or the like. In other embodiments,the outlet 836 can be coupled to a transfer adapter and/or the like suchas, for example, the transfer adapters described in the ‘352publication. Accordingly, the outlet 836 can place the control device800 in fluid communication with a fluid collection device coupled to thetransfer adapter and/or the like. As described above with reference tothe outlet 136 of the control device 100, the outlet 836 of the controldevice 800 can be in a sealed or closed configuration when the controldevice 800 is in a first state and can be transitioned to an openconfiguration when the control device 800 is transitioned to a secondstate. The fluid collection device can be any suitable device, syringe,reservoir, and/or container such as those described above with referenceto the control device 100 and thus, is not described in further detailherein. In other embodiments, the outlet 836 can be physically and/orfluidically coupled to any suitable device such as, for example, asyringe or other suitable fluid collection device.

As described in detail above with reference to the devices 100, 200,300, 400, 500, 600, and/or 700, the device 800 can be used to divert(e.g., passively divert) and/or otherwise facilitate a flow of a firstor initial volume of bodily fluid such that subsequently procured bodilyfluid samples have reduced contamination from microbes such as, forexample, dermally residing microbes and/or the like. For example, insome instances, a user such as a doctor, physician, nurse, phlebotomist,technician, etc. can manipulate the device 800 by inserting at least aportion of an inlet device such as, for example, a needle, into apatient's vein (e.g., a venipuncture event) and/or can otherwiseestablish fluid communication between the needle and the patient. Oncein fluid communication with the patient, bodily fluid can flow from thebodily fluid source (e.g., the vein of the patient), through the inlet832 and into the control device 800. In some embodiments, the controldevice 800 can be in and/or can be placed in a first or initial state inwhich an initial portion or volume of bodily fluid can flow in orthrough at least a portion the fluid flow path 833 and into thesequestration portion 834.

The initial portion and/or volume of bodily fluid can be any suitablevolume of bodily fluid, as described above. In some instances, thecontrol device 800 can remain in the first state until a predeterminedand/or desired volume (e.g., the initial volume) of bodily fluid istransferred to the sequestration portion 834. In the embodiment shown inFIGS. 21 and 22, the initial volume can be associated with and/or atleast partially based on an amount or volume of bodily fluid that can beabsorbed by the hydrophilic material 840 (e.g., flow controller).Furthermore, the initial volume can be associated with and/or at leastpartially based on the vent material 842 transitioning to a sealedconfiguration, as described above. In some embodiments, the hydrophilicmaterial 840 becoming saturated (e.g., after absorbing a maximum amountof bodily fluid or substantially a maximum amount) and the vent material842 becoming saturated (e.g., such that the vent material 842transitions to the sealed configuration) can occur substantiallyconcurrently in response to the same, predetermined volume of bodilyfluid being transferred into the sequestration portion 834 (i.e., theinitial volume). After the initial volume of bodily fluid is transferredand/or diverted into the sequestration portion 834, the initial volumeis sequestered, segregated, retained, contained, isolated, etc. in thesequestration portion 834. As described above, contaminants such as, forexample, dermally residing microbes or the like dislodged during thevenipuncture event, can be entrained and/or included in the initialvolume of the bodily fluid and thus, can also be sequestered in thesequestration portion 834 when the initial volume is sequesteredtherein.

With the initial volume sequestered in the sequestration portion 834,the device 800 can transition to the second state in which a subsequentvolume(s) of bodily fluid can flow through at least a portion the fluidflow path 833 from the inlet 832, through the junction 817, and to theoutlet 836. In the embodiment shown in FIGS. 21 and 22, the controldevice 800 is configured to automatically transition (e.g., without userintervention) from the first state to the second state once the initialvolume of bodily fluid is sequestered in the sequestration portion 834.For example, filling the sequestration portion 834 to capacity and/orsaturating, wetting, and/or impregnating the hydrophilic material 840and/or the vent material 842 can limit and/or substantially prevent anyadditional volume of bodily fluid from being transferred into thesequestration portion 834. In addition, saturating, wetting, and/orimpregnating the hydrophilic material 840 and/or the vent material 842can limit and/or substantially prevent any fluid flow out of thesequestration portion 834 and back into the fluid flow path 833. In someembodiments, the transitioning of the control device 800 can be at thejunction 817 and/or can be a result of the junction 817 transitioningfrom a first state to a second state. Thus, as a subsequent flow and/orvolume of bodily fluid enters the fluid flow path 833, the controldevice 800 directs, diverts, and/or otherwise facilitates a subsequentvolume of bodily fluid flowing in the flow path 833 to flow through thejunction 817 and to, toward, or through the outlet 836.

Although not shown in FIGS. 21 and 22, the outlet 836 can be fluidicallycoupled to a fluid collection device before or after the control device800 transitions to the second state. In some embodiments, thearrangement of the outlet 836 can be such that the outlet 836 remainssealed until the initial volume of bodily fluid is sequestered in thesequestration portion 834. Accordingly, with the fluid collection devicefluidically coupled to the outlet 836 and with the control device 800being in the second state, any subsequent volume(s) of the bodily fluidcan flow from the inlet 832, through the fluid flow path 833 (e.g., atleast partially defined by the inlet 832, a portion of the junction 817,and the outlet 836), and into the fluid collection device. Thus, asdescribed above, sequestering the initial volume of bodily fluid in thesequestration portion 834 prior to collecting or procuring one or moresample volumes of bodily fluid reduces and/or substantially eliminatesan amount of contaminants in the one or more sample volumes. Moreover,in some embodiments, the arrangement of the control device 800 can besuch that control device 800 directs, diverts, and/or otherwisefacilitates the flow into the sequestration portion 834 prior todirecting, diverting, and/or otherwise facilitating the flow to theoutlet 836. In other words, the control device 800 is configured toforce compliance such that the control device 800 cannot transition tothe second state prior to collecting and sequestering the initial volumein the sequestration portion 834.

While the control device 800 is shown and described above as having thehydrophilic material 840 and the vent material 842 disposed in thesequestration portion 834, in other embodiments, a control device caninclude a sequestration and/or diversion portion (e.g., chamber,reservoir, lumen, channel, etc.) having any suitable configuration. Forexample, as described above with reference to the sequestration portion134, in some embodiments, the sequestration portion 834 can include ahydrophilic coating or surface finish. While the vent material 842 isdescribed as being an absorbent material and/or a selectively permeablemember or membrane, in other embodiments, the sequestration portion 834can include a vent that is formed with or by a one-way valve or thelike. In some embodiments, such a valve can be gas permeable and liquidimpermeable. In some embodiments, such a valve can be user actuated,fluid actuated, pressure actuated, time-based, etc. In some embodiments,the sequestration portion 834 can include a combination of the ventmaterial 842 and a valve or other means of flow control. In someembodiments, the sequestration portion 834 can include a one-way valveand the vent material 842 that can collectively act to vent thesequestration portion 834. In such embodiments, the one-way valve can bedisposed in any suitable position relative to the vent material 842(e.g., upstream or downstream relative to the vent material 842).

As described above, a sequestration portion can have any suitablegeometry or shape configured to enhance and/or facilitate wicking and/orabsorption. For example, FIGS. 23 and 24 illustrate a fluid controldevice 900 according to another embodiment. As described previously withreference to the control devices 100, 200, 300, 400, 500, 600, 700,and/or 800, the fluid control device 900 (also referred to herein as“control device” or “device”) is configured to withdraw and sequester afirst portion or amount (e.g., an initial amount) of bodily fluid from apatient such that any subsequently withdrawn amount, portion, and/orvolume of bodily fluid is substantially free of contaminants. In someembodiments, portions and/or aspects of the control device 900 aresubstantially similar in form and/or function to the correspondingportions and/or aspects of the control devices 100, 200, 300, 400, 500,600, 700, and/or 800 described above. Accordingly, such similar portionsand/or aspects are not described in further detail herein.

The control device 900 can be any suitable device or set of devicesconfigured to (1) receive a flow of bodily fluid, (2) store andsequester a first volume or initial volume of the bodily fluid, and (3)direct, divert, and/or otherwise facilitate a subsequent flow of thebodily fluid to a fluid collection device (not illustrated). In theembodiment illustrated in FIGS. 23 and 24, the control device 900includes an inlet 932 (or inlet portion) and an outlet 936 (or outletportion), and defines a sequestration and/or diversion portion 934 (alsoreferred to herein as “sequestration portion”).

The inlet 932 formed by and/or included in the control device 900 isconfigured to be fluidically coupled to an inlet device (not shown inFIGS. 23 and 24) to place the control device 900 in fluid communicationwith a bodily fluid source such as, for example, the vasculature of apatient. Although not specifically shown in FIGS. 23 and 24, the inlet932 can be any suitable inlet, opening, port, lock, seal, coupler, etc.,as described above with reference to the inlet 832. Similarly, the inletdevice (configured to be coupled to or otherwise in fluid communicationwith the inlet 932) can be any suitable device or set of devices. Forexample, in some embodiments, the inlet device can be a lumen-containingdevice (e.g., a needle, catheter, etc.), a port, a valve, and/or anyother suitable coupler, as described in detail above. Thus, the inlet932 and the inlet device are not described in further detail herein.

The outlet 936 formed by and/or included in the control device 900 isconfigured to be fluidically coupled to a fluid collection device.Although not specifically shown in FIGS. 23 and 24, the outlet 936 canbe any suitable outlet, opening, port, lock, seal, coupler, etc., asdescribed in detail above. In some embodiments, the outlet 936 caninclude and/or can be coupled to an outlet needle, a transfer adaptersuch as, for example, the transfer adapters described in the ‘352publication, a sample reservoir, a syringe, and/or any other suitabledevice or collection member. Accordingly, the outlet 936 is configuredto place the control device 900 in fluid communication with a samplereservoir (or other suitable device). As such, the outlet 936 can besimilar to or substantially the same as the outlets 136, 236, 336, 436,536, 636, 736, and/or 836. Likewise, the fluid collection deviceconfigured to be coupled to the outlet 936 can be similar to orsubstantially the same as any of the fluid collection devices describedabove. Accordingly, the outlet 936 and the fluid collection devicecoupled to the outlet 936 are not described in further detail herein.

The control device 900 can be any suitable shape, size, and/orconfiguration. For example, in some embodiments, the control device 900can be formed of a relatively rigid material such as a plastic or thelike and can be configured to retain its shape and/or form when exposedto changes in pressure and/or inlet and outlet flows of fluid. In someembodiments, some portions of the control device 900 can be formed of arelatively rigid material while some other portions of the controldevice 900 can be formed of relatively flexible material such asflexible plastic, rubber, or the like.

As described above with reference to the control device 800, the controldevice 900 defines one or more fluid flow paths 933 between the inlet932 and the sequestration portion 934 and/or between the inlet 932 andthe outlet(s) 936. In some embodiments, the control device 900 can beconfigured such that a first portion of the fluid flow path 933 (alsoreferred to herein as “flow path”) places the inlet 932 in selectivefluid communication with the sequestration portion 934, and a secondportion of the flow path 933 places the inlet 932 in selective fluidcommunication with the outlet 936. In some embodiments, the inlet 932(or inlet portion), the sequestration portion 934 (or portion thereof),and the outlet 936 (or outlet portion) can include and/or can be formedwith or by one or more tubes or other lumen-containing devices, coupledto each other through one or more suitable couplers or ports (e.g., aT-connector, Y-connector, and/or any other suitable coupler(s)) orattached to each other through any suitable mechanism to form portionsof a continuous fluid flow path (e.g., the flow path 933). Moreparticularly, in some embodiments, the control device 900 can include ajunction 917 or the like collectively formed at or near a connection ofthe inlet 932 (or inlet portion), the sequestration portion 934 (orportion thereof), and the outlet 936 (or outlet portion). As describedin further detail herein, in some embodiments, the control device 900can be configured to transition at or near the junction 917 to control aflow of bodily fluid therethrough, as described above with reference tothe control device 800. Accordingly, the control device 900 can besimilar in at least form or function to the control device 800 describedin detail above with reference to FIGS. 21 and 22, except for thedifferences described below, and thus, such similar portions and/oraspects of the control device 900 are not described in further detailherein.

The control device 900 can differ from the control device 800, forexample, in the arrangement and/or shape of the sequestration portion934. For example, while the sequestration portion 834 of the controldevice 800 has a relatively shallow cylindrical shape, the sequestrationportion 934 in the control device 900 can have and/or can assume afan-like shape, as indicated by side view illustration in FIG. 23 andthe cross-sectional view in FIG. 24. The sequestration portion 934 caninclude a hydrophilic material 940 (e.g., flow controller) disposedtherein, and the hydrophilic material 940 can conform to any suitableshape (e.g., the shape of the sequestration portion 934), as describedbelow. The hydrophilic material 940 can be of a suitable material toabsorb wick, pump, and/or otherwise encourage bodily fluid flow, drawingin more bodily fluid from the source of bodily fluid via the inlet 932.The sequestration portion 934 and/or the hydrophilic material 940disposed therein is at least temporarily placed in fluid communicationwith the inlet 932 via the fluid flow path 933 and is configured to (1)receive a flow and/or volume of bodily fluid from the inlet 932 and (2)sequester (e.g., separate, segregate, contain, retain, isolate, etc.)the flow and/or volume of bodily fluid therein. In some embodiments, thehydrophilic material 940 can be substantially similar to the hydrophilicmaterial 840 disposed in the sequestration portion 834.

The hydrophilic material 940 can have any suitable geometry, size,and/or configuration. For example, as shown in the embodimentillustrated in FIGS. 23 and 24, the hydrophilic material 940 assumes ashape that matches the shape and geometry of the sequestration portion934. That is, in this embodiment, the hydrophilic material 940 assumes atwo-layered fan shape defining a space or gap 945 between the two layersof hydrophilic material 940 to allow fluid flow from the fluid flow path933 into the sequestration portion 934. The fan-shaped form of thehydrophilic material 940 can be configured to facilitate a substantiallyfree flow of the bodily fluid drawn into the sequestration portion 934without clogging, and the gap or space 945 can allow for an expansion ofthe hydrophilic material 940, which in turn, can aid in establishing anegative pressure differential between the sequestration portion 934 andat least a portion of the fluid flow path 933, thereby enhancing thedrawing, wicking, or pumping action of the hydrophilic material 940disposed in the sequestration portion 934.

In some embodiments, the expansion of the hydrophilic material 940 inthe two-layered, fan-shaped form, for example, in response to theabsorption of bodily fluid, increases the volume of the hydrophilicmaterial 940, which in turn, draws in bodily fluid (e.g., via capillaryaction, wicking, absorption, etc.). In some embodiments, the specificshape of the sequestration portion 934 and the hydrophilic material 940can be configured to result in a desired and/or predetermined flow ofbodily fluid into the sequestration portion 934. For example, thefan-shaped form of the sequestration portion 934 and the hydrophilicmaterial 940, in the embodiment illustrated in FIGS. 23 and 24, includesan increasing volume of the sequestration portion 934 and thehydrophilic material 940 (and/or other absorbent material) due to thebroadening of the width of the sequestration portion 934 and thehydrophilic material 940. In some instances, this configuration can leadto a greater absorption along the radius of the fan-shaped form of thehydrophilic material 940 and/or sequestration portion 934. Moreover, insome instances, the increasing volume of the sequestration chamber 934can result in a pressure differential and/or gradient that can aid indrawing bodily fluid into the sequestration chamber 934. The space 945defined by the hydrophilic material 940 can form a channel to allowfluid flow into the sequestration portion 934, without clogging,clumping, or other sources of disruption of the drawing, wicking, and/orpumping action associated with the expansion of the hydrophilic material940.

The sequestration portion 934 can also define an opening 935 and caninclude a vent material 942 (e.g., flow controller) disposed within theopening 935. Similar to the description above with reference to the ventmaterial 842 disposed in the opening 835 of the control device 800, thevent material 942 can be configured to vent the sequestration portion934 through the opening 935. The opening 935 and/or the vent material942 can be configured to transition from an open or ventingconfiguration and/or state prior to the sequestration portion 934receiving a first or initial volume of bodily fluid, to a sealed,closed, and/or otherwise not vented configuration, after the first orinitial volume of bodily fluid has flowed into the sequestration portion934. In some embodiments, the sequestration portion 934 can be vented toa volume outside of the sequestration portion 934 (e.g., an ambientenvironment). For example, in some embodiments, the opening 935 or thelike can receive a volume or flow of air or gas that is displaced as thehydrophilic material 940 expands. In some embodiments, the vent material942 can be similar or substantially the same as the vent material 842included in the control device 800. In some embodiments, the arrangementof the hydrophilic material 940 can be such that the opening 935 neednot include the vent material 942 and/or any other selectively permeablemember or membrane to prevent the venting or escaping of bodily fluid(e.g., a portion of the hydrophilic material 940 is disposed in or aboutthe opening 935 and functions similarly to the vent material 942). Assuch, the hydrophilic material 940 and the vent material 942 each can bea flow controller or can collectively be a flow controller configured toselectively control a flow of fluid (e.g., gas and/or liquid) into andout of the sequestration portion 934.

As described in detail above with reference to previous embodiments, thedevice 900 shown in FIGS. 23 and 24 can be used to divert (e.g.,passively) a first or initial volume of bodily fluid such thatsubsequently procured bodily fluid samples have reduced contaminationfrom microbes such as, for example, dermally residing microbes and/orthe like. In some embodiments, the control device 900 can be in and/orcan be placed in a first or initial state in which an initial portion orinitial volume of bodily fluid can flow in or through at least a portionthe fluid flow path 933, through at least a portion of the junction 917,and into the sequestration portion 934.

The initial portion and/or volume of bodily fluid can be any suitablevolume of bodily fluid, as described above. For example, the initialvolume can be associated with and/or at least partially based on anamount or volume of bodily fluid that can be stored, contained, and/orsequestered in or by the sequestration portion 934 and/or thehydrophilic material 940. After the initial volume of bodily fluid istransferred and/or diverted into the sequestration portion 934, theinitial volume is sequestered, segregated, retained, contained,isolated, etc. in the sequestration portion 934. For example, in someembodiments, transferring the initial portion or volume of bodily fluidinto the sequestration portion 934 can place the hydrophilic material940 (and/or any other suitable flow controller) in an expanded stateand/or configuration and, as such, the hydrophilic material 940 cansubstantially prevent any subsequent volume of bodily fluid from beingdisposed in the sequestration portion 934. Further, in some embodiments,when the hydrophilic material 940 is in the expanded state, the centralspace or gap 945 defined by the hydrophilic material 940, operable toallow fluid flow into the sequestration portion 934 without clogging orotherwise disrupting the pump or wicking action of the hydrophilicmaterial 940, can be reduced, shrunk, narrowed, and/or closed in. Insome instances, closing of the space 945 can prevent any subsequentvolume of bodily fluid from flowing into and/or out of the sequestrationportion 934.

In some embodiments, once the hydrophilic material 940 is expanded, apressure differential associated with and/or resulting from theexpansion of hydrophilic material 940 can be reduced and/orsubstantially equalized such that no subsequent volume of bodily fluidis “drawn” into the sequestration portion 934 and/or the hydrophilicmaterial 940. That is to say, once the hydrophilic material 940 isplaced in an expanded configuration, the negative pressure otherwiseassociated with the hydrophilic material 940 absorbing the bodily fluidis substantially equalized. In some embodiments, the vent material 942can absorb bodily fluid and expand or be saturated in a manner similarto the hydrophilic material 940, thereby placing the vent material 942in a sealed, closed, or impermeable state. In some embodiments, thesaturation of the hydrophilic material 940 and/or the saturation of thevent material 942 can occur concurrently and can collectively limitand/or substantially prevent a subsequent flow of fluid into and/or outof the sequestration portion 934. In other embodiments, at least aportion of the junction 917 leading to the sequestration portion 934 caninclude a valve, a selectively permeable membrane, fluid activated(e.g., bodily fluid activated) switch or seal, user activated switch orseal, and/or the like that can limit and/or substantially prevent a flowof bodily fluid into and/or out of the sequestration portion 934. Asdescribed above, contaminants such as, for example, dermally residingmicrobes or the like dislodged during the venipuncture event, can beentrained and/or included in the initial volume of the bodily fluid andthus, can also be sequestered in the sequestration portion 934 when theinitial volume is sequestered therein.

With the initial volume sequestered in the sequestration portion 934,the device 900 can transition to the second state in which a subsequentvolume(s) of bodily fluid can flow through at least a portion the fluidflow path 933 from the inlet 932, through the junction 917, and to theoutlet 936. In the embodiment shown in FIGS. 23 and 24, the controldevice 900 is configured to automatically transition (e.g., without userintervention) from the first state to the second state once the initialvolume of bodily fluid is sequestered in the sequestration portion 934.Thus, as a subsequent flow and/or volume of bodily fluid enters thefluid flow path 933, the control device 900 directs and/or diverts theflow through a portion of the fluid flow path 933 (e.g., through thejunction 917) and to the outlet 936. As described in detail above, theoutlet 936 is configured to be placed in fluid communication with one ormore fluid collection devices such that the subsequent volume(s) of thebodily fluid can flow from the inlet 932, through the fluid flow path933, the junction 917, and the outlet 936, and into the fluid collectiondevice (not shown). Thus, as described above, sequestering the initialvolume of bodily fluid in the sequestration portion 934 prior tocollecting or procuring one or more sample volumes of bodily fluidreduces and/or substantially eliminates an amount of contaminants in theone or more sample volumes.

In some embodiments, the arrangement of the junction 917, thesequestration portion 934, and/or the hydrophilic material 940 disposedin the sequestration portion 934 can be such that the initial volume ofbodily fluid is retained in the sequestration portion 934 despite atleast partially being exposed to a negative pressure differentialproduced by the fluid collection device. In some embodiments, thesequestration portion 934 and/or junction 917 can include an orifice orentrance into the sequestration portion 934 that includes a valve,switch, or actuator. The valve, switch, or actuator (or any othersuitable flow controller) can limit and/or substantially prevent anoutflow of the bodily fluid from the sequestration portion 934 inresponse to a negative pressure or the like produced by the fluidcollection device. That is to say, sequestration portion 934 isconfigured to retain and/or sequester the initial volume of bodily fluiddespite at least partially being exposed to a negative pressuredifferential produced by the fluid collection device.

While some devices are described herein as including sequestrationand/or diversion portions that have one or more flow controllersarranged as absorbent, hydrophilic, and/or selectively permeablemembers, in other embodiments, a control device can include asequestration and/or diversion portion that can include any suitableflow controller configured to draw bodily fluid into the sequestrationchamber. For example, FIG. 25 illustrates a fluid control device 1000according to an embodiment. As described above with reference to thedevices 100, 200, 300, 400, 500, 600, 700, 800, and/or 900, the fluidcontrol device 1000 (also referred to herein as “control device” or“device”) is configured to withdraw and sequester a first portion oramount (e.g., an initial amount) of bodily fluid from a patient suchthat any subsequently withdrawn amount, portion, and/or volume of bodilyfluid is substantially free of contaminants. In some embodiments,portions, features, and/or aspects of the device 1000 are substantiallysimilar in form and/or function to the corresponding portions, features,and/or aspects of the devices 100, 200, 300, 400, 500, 600, 700, 800,and/or 900 described above. Accordingly, such similar portions,features, and/or aspects are not described in further detail herein.

The control device 1000 can be any suitable device or set of devicesconfigured to (1) receive a flow of bodily fluid, (2) store andsequester a first volume or initial volume of the bodily fluid, and (3)direct, divert, and/or otherwise facilitate a subsequent flow of thebodily fluid to a fluid collection device (not illustrated). In theembodiment shown in FIG. 25, the control device 1000 includes an inlet1032 (or inlet portion) and an outlet 1036 (or outlet portion), anddefines a sequestration and/or diversion portion 1034 (also referred toherein as “sequestration portion”). The control device 1000 includesand/or forms a junction 1017 or the like formed at or near a connectionof the inlet 1032 (or inlet portion), the sequestration portion 1034 (orportion thereof), and the outlet 1036 (or outlet portion). Furthermore,the control device 1000 defines a fluid flow path 1033 (also referred toherein as “flow path”) that places the inlet 1032 (or inlet portion) inselective fluid communication with the sequestration portion 1034 and/orthe outlet 1036 (or outlet portion). As described in further detailherein, in some embodiments, the control device 1000 can be configuredto transition at or near the junction 1017 to control bodily fluidflowing through the flow path 1033, as described above with reference tothe control devices 800, and/or 900.

The inlet 1032 formed by and/or included in the control device 1000 isconfigured to place the control device 1000 in fluid communication witha bodily fluid source (e.g., via an access or inlet device), asdescribed in detail above. The outlet 936 formed by and/or included inthe control device 900 is configured to be fluidically coupled to afluid collection device (e.g., a syringe, evacuated container, dish,sampling device or machine, etc.). Although not specifically shown inFIG. 25, the outlet 1036 can be any suitable outlet, opening, port,lock, seal, coupler, etc., as described above with reference to theoutlets 136, 236, 336, 436, 536, 636, 736, 836 and/or 936. Accordingly,the outlet 1036 is configured to place the control device 1000 in fluidcommunication with a fluid collection device (or other suitable device),as described in detail above. Thus, the inlet 1032 (e.g., coupleable toan inlet device) and the outlet 1036 (e.g., coupleable to a fluidcollection device) are not described in further detail herein and shouldbe considered similar to any of the inlets and/or outlets describedabove with reference to previous embodiments, unless explicitly statedotherwise.

The control device 1000 can differ from the control devices 100, 200,300, 400, 500, 600, 700, 800, and 900, however, in the arrangement ofthe sequestration portion 1034. For example, the sequestration portion1034 shown in FIG. 25 is configured to include one or more flowcontrollers having a shape, geometry, and/or structure configured todraw or aid in the drawing of a flow of bodily fluid into thesequestration portion 1034. In other words, bodily fluid can flow withinthe fluid flow path 1033 of the control device 1000 from the inlet 1032,through the junction 1017, into or through the sequestration portion1034, and into or through the flow controller (and/or other suitablestructure(s)) defined or formed within the sequestration portion 1034that act to draw or wick fluid into the sequestration portion 1034.

For example, as illustrated in FIG. 25, the sequestration portion 1034can include a series of capillary tubes 1050 (e.g., flow controller(s))each of which has a high surface area to volume ratio operable to drawfluid flow through the capillary tube(s) 1050. Each of the capillarytubes 1050 can have a desired diameter and can extend a desired lengthacross or within the sequestration portion 1034. As shown, the capillarytubes 1050 can occupy a desired portion in a desired location of thesequestration portion 1034 such that bodily fluid can from the inlet1032 into the sequestration portion 1034 (e.g., the capillary tubes 1050need not occupy all of the sequestration portion 1034). The number andshape of the capillary tubes 1050 can at least partially be designed todetermine the volume of bodily fluid drawn into the sequestrationportion 1034. Although the sequestration portion 1034 is described asincluding one or more capillary tubes 1050 operable to draw bodily fluidinto the sequestration portion 1034 (e.g., via capillary action,wicking, etc.), in other embodiments, a sequestration chamber caninclude any suitable material, structure, formation, feature, etc.configured to draw bodily fluid into the sequestration chamber viacapillary action, wicking, and/or any other suitable mode.

In some embodiments, the sequestration portion 1034 can be vented and/orcan include an opening or vent configured to selectively vent thesequestration portion 1034 to a volume outside of the sequestrationportion 1034 (e.g., the ambient environment). For example, in someembodiments, the sequestration portion 1034 can define an opening 1035or the like that can receive a volume or flow of air or gas that isdisplaced as the capillary tubes 1050 are filled with and/or otherwisedraw in bodily fluid. In some embodiments, as described previously, thesequestration portion 1034 can include a vent material 1042 or the likedisposed within and/or about the opening 1035. The vent material 1042can be similar to or substantially the same as the vent material 842and/or 942 included in the control devices 800 and/or 900, respectively.Accordingly, the vent material 1042 is not further described in detailhere. In other embodiments, the arrangement of the capillary tubes 1050can be such that the sequestration portion 1034 need not include thevent material or the like disposed in and/or about the opening.

As described in detail above with reference to the devices 100, 200,300, 400, 500, 600, 700, 800, and/or 900, the device 1000 shown in FIG.25 can be used to direct or divert (e.g., passively) a first or initialvolume of bodily fluid such that subsequently procured bodily fluidsamples have reduced contamination from microbes such as, for example,dermally residing microbes and/or the like. For example, in someinstances, a user such as a doctor, physician, nurse, phlebotomist,technician, etc. can manipulate the device 1000 to establish fluidcommunication between, for example, an inlet device and the patientand/or other bodily fluid source. Moreover, the arrangement of thecontrol device 1000 can be such that the inlet 1032 is coupled to and/orotherwise includes the inlet device and thus, the control device 1000 islikewise placed in fluid communication with the patient and/or otherbodily fluid source. In some embodiments, the control device 1000 can bein and/or can be placed in a first or initial state in which an initialportion or volume of bodily fluid can flow in or through at least aportion the fluid flow path 1033, through the junction 1017, and intothe sequestration portion 1034.

As described in detail above, the initial portion and/or volume ofbodily fluid can be any suitable volume of bodily fluid. For example, insome instances, the control device 1000 can remain in the first stateuntil a predetermined and/or desired volume (e.g., the initial volume)of bodily fluid is transferred to the sequestration portion 1034. Insome embodiments, the initial volume can be associated with and/or atleast partially based on an amount or volume of bodily fluid that can bedrawn, stored, contained, and/or sequestered in the series of capillarytubes 1050. After the initial volume of bodily fluid is transferredand/or diverted into the sequestration portion 1034, the initial volumeis sequestered, segregated, retained, contained, isolated, etc. in thesequestration portion 1034.

For example, in some embodiments, transferring the initial portion orvolume of bodily fluid into the portion of the sequestration portion1034 including the capillary tubes 1050 can fill the capillary tubes1050 such that no further volume of bodily fluid is drawn therein (e.g.,via capillary action, wicking, etc.). Further, in some embodiments,filling the capillary tubes 1050 and/or otherwise filling orsubstantially filling the sequestration portion 1034 can result inand/or can be in response to a reduction in a pressure differentialbetween, for example, the junction 1017 and at least a portion of thesequestration portion 1034. For example, in some embodiments, filling orsubstantially filling the sequestration portion 1034 can transition thevent material 1042 (e.g., flow controller) from a first state in whichthe vent material 1042 allows venting of the sequestration portion 1034through the opening 1035 to a second state in which the vent material1042 is saturated, sealed, and/or otherwise prevents a venting throughthe opening 1035, which in turn, can result in and/or can allowpressures to equalize.

In some embodiments, the filling of the capillary tubes 1050 and thesaturation of the vent material 1042 can occur concurrently and canlimit and/or at least partially prevent subsequent flow of fluid into orout of the sequestration portion 1034. In other words, the capillarytubes 1050 and the vent material 1042 each can be a flow controller orcollectively can be a flow controller configured to at least partiallycontrol a flow of fluid into and/or out of the sequestration portion1034. In some embodiments, the device 1000 and/or the junction 1017 caninclude a valve, a selectively permeable membrane, fluid activated(e.g., bodily fluid activated) switch or seal, user activated switch orseal, and/or the like that can limit and/or substantially prevent a flowof bodily fluid into or out of the sequestration portion 1034. Moreover,as described previously, in some embodiments, the arrangement of thedevice 1000, the junction 1017, and/or the sequestration portion 1034can be such that the initial volume of bodily fluid is retained and/orsequestered in the sequestration portion 1034 despite the introductionof a negative pressure differential associated with establishing fluidcommunication between the outlet and a fluid collection device.

With the initial volume sequestered in the sequestration portion 1034,the device 1000 can transition to the second state in which a subsequentvolume(s) of bodily fluid can flow through at least a portion the fluidflow path 1033 from the inlet 1032, through the junction 1017 and theoutlet 1036, and into a fluid collection device fluidically coupled tothe outlet 1036. In the embodiment shown in FIG. 25, the control device1000 is configured to automatically transition (e.g., without userintervention) from the first state to the second state once the initialvolume of bodily fluid is sequestered in the sequestration portion 1034.For example, in some embodiments, transferring the initial volume ofbodily fluid into the sequestration portion 1034 can result in, canallow, and/or otherwise can be operable to transition the junction 1017from a first state in which bodily fluid can flow from the inlet 1032toward the sequestration portion 1034 to a second state in which bodilyfluid can flow from the inlet 1032 toward the outlet 1036. Thus, as asubsequent flow and/or volume of bodily fluid enters the fluid flow path1033, the control device 1000 and/or the junction 1017 directs and/ordiverts the flow through a portion of the fluid flow path 1033, aportion of the junction 1017, and the outlet 1036, and into one or morefluid collection devices fluidically coupled thereto (e.g., samplereservoir(s), syringe(s), transfer adapters, etc.).

FIG. 26 illustrates a fluid control device 1100 according to anotherembodiment. The fluid control device 1100 can be any suitable device orset of devices configured to (1) receive a flow of bodily fluid, (2)store and sequester a first volume or initial volume of the bodilyfluid, and (3) direct, divert, and/or otherwise facilitate a subsequentflow of the bodily fluid to a fluid collection device (not illustrated).In the embodiment shown in FIG. 26, the control device 1100 includes aninlet 1132 (or inlet portion), an outlet 1136 (or outlet portion), and ajunction 1117, and includes and/or defines one or more fluid flow paths1133 and a sequestration and/or diversion portion 1134 (also referred toherein as “sequestration portion”). The inlet 1132 is configured to beplaced in fluid communication with a bodily fluid source (eitherdirectly or indirectly), as described in detail above. The outlet 1136is configured to be coupled to a fluid collection device (not shown), asdescribed in detail above. Accordingly, the inlet 1132 and outlet 1136are not described in further detail herein.

As described with respect to previous devices (e.g., devices 100, 200,300, 400, 500, 600, 700, 800, 900, and/or 1000) the control device 1100can have any suitable size and/or shape. For example, the control device1100 illustrated in FIG. 25 forms a bifurcation (e.g., a Y-shapedbifurcation, T-shaped bifurcation, and/or the like). More specifically,the inlet 1132 or inlet portion, the outlet 1136 or outlet portion, andthe sequestration portion 1134 or portion thereof are coupled, joined,and/or otherwise meet at the junction 1117. The junction 1117, in turn,is configured to selectively establish fluid communication between theinlet 1132 or inlet portion and the sequestration portion 1134 orportion thereof, and between the inlet 1132 or inlet portion and theoutlet 1136 or outlet portion, as described in further detail herein.While the control device 1100 is shown in FIG. 26 as forming theY-shaped bifurcation, in other embodiments, the control device 1100 canform any suitable shape and/or can have any suitable configuration orarrangement.

The sequestration portion 1134 can be of any shape and/or size to drawin sufficient volume of the bodily fluid (e.g., a desired initialvolume). In some embodiments, the sequestration portion 1134 can includea flow controller and/or the like configured to transition between afirst state and a second state to draw or aid in drawing bodily fluidinto sequestration portion 1134. For example, in the embodimentillustrated in FIG. 26, the sequestration portion 1134 can include anactuator 1151 (e.g., a flow controller) configured to be actuated and/ormoved within the sequestration portion 1134 in response to contact withat least a portion of the initial volume of bodily fluid. Moreparticularly, the actuator 1151 can be and/or can include a plunger or apiston, disposed within and capable of movement along an axis of thesequestration portion 1134. In some embodiments, the actuator 1151 canbe configured to separate, divide, sequester, and/or otherwise partitiona first volume of the sequestration portion 1134 that is configured tobe in fluidic communication with the inlet 1132 of the control device1100, from a second volume of the sequestration portion 1134 that is notin fluidic communication with or is otherwise fluidically isolated fromthe inlet 1132, as shown in FIG. 26.

The actuator 1151 is disposed within the sequestration portion 1134 suchthat movement of the actuator 1151 can define and/or can result in achange of the relative sizes of the first and second volumes of thesequestration portion 1134. For example, prior to use, the actuator 1151can be in an initial state or position and can be held and/or retainedin the initial state or position via one or more active or passivemechanisms and/or means. In some embodiments, while in the initialstate, the actuator 1151 or a portion thereof can have a relatively highpotential energy and/or can be disposed in a configuration associatedwith a relatively high potential energy. In such embodiments, theactuator 1151 can be configured such that the activation of the actuator1151 converts that potential energy into other suitable forms, forexample, kinetic energy, etc. In other embodiments, the actuator 1151can be held in an initial state at rest and the activation can involveactively moving the actuator 1151 away from the initial resting state(e.g., as described below with reference to the embodiment illustratedin FIG. 27).

As shown in FIG. 26, the sequestration portion 1134 includes a spring1154 connecting the plunger 1151 to a wall or surface of thesequestration portion 1134. In some embodiments, the initial state ofthe actuator 1151 can be such that the spring 1154 is loaded with apredetermined and/or desired tension prior to use (e.g., duringmanufacture and/or assembly of the device 1100) such that when theactuator 1151 is at the initial position the spring 1154 is in tension.In other words, when the actuator 1151 is in the initial state orposition, the spring 1154 can be in a state or configuration having arelatively high potential energy. In such embodiments, the actuator 1151can be held in place in the initial state and/or position though the useof one or more components like an adhesive, glue, physical stoppers, orthe like, acting through mechanisms, which when removed, released,dissolved, or deactivated can allow the tension in the spring 1154 to bereleased, thereby moving the actuator 1151 (or piston or plungerthereof) away from the initial state and/or position. That is to say,when the one or more components is/are removed, released, dissolved,transitioned, and/or deactivated, the actuator 1151 and spring 1154 canbe transitioned (e.g., from the conversion of potential energy tokinetic energy) from the initial state or position having the relativelyhigh potential energy to a subsequent state or position having arelatively low potential energy.

As an example, the device 1100 in FIG. 26 can include a dissolvablebonding substance 1155 (e.g., glue, adhesive, fastener, epoxy, foam,and/or the like) that at least temporarily bonds the actuator 1151 toone or more surfaces of the sequestration portion 1134 until it isdissolved, for example, by contact with a flow of bodily fluid into thesequestration portion 1134. In some embodiments, the amount of thedissolvable bonding substance 1155 can be dependent at least partiallyon the amount of a bonding, adhesive, and/or friction force sufficientto hold the actuator 1151 in the initial state (e.g., sufficient toexert a reaction force in response to forces resulting from the weightof the actuator 1151, the properties of the spring 1154 such as springrate, material properties, amount of tension in the spring 1154, etc.,and/or the like). In some embodiments, the amount of the dissolvablebonding substance 1155 can be dependent at least partially on a desiredamount of bodily fluid sufficient to substantially dissolve thedissolvable bonding substance 1155 to release the actuator 1151 awayfrom the initial state.

In some embodiments, the actuator 1151 can be suitably configured inform, shape, size, surface, etc., to facilitate the temporary bonding ofthe actuator 1151 to the surface(s) or wall(s) of the sequestrationportion 1134 using the bonding substance 1155. For example, the actuator1151 can include and/or can have a surface area and/or a surface finishthat increases and/or facilitates adhesion. In some embodiments, atleast a portion of the actuator 1151 can be formed of a porous and/orabsorbent material configured to increase and/or facilitate adhesion toand/or with the bonding substance 1155. In the embodiment shown in FIG.26, the actuator 1151 can include protrusions (e.g., finger-likeprotrusions or the like) extending toward the inlet 1132 or junction1117, which are at least temporarily in contact with the dissolvablebonding substance 1155. In such embodiments, the protrusions can beconfigured to increase an amount of surface area of the actuator 1151that is placed in contact with the dissolvable bonding substance 1155.In other embodiments, the actuator 1151 and/or a portion thereof canhave any suitable shape, size, or surface finish and/or can be formed ofany suitable material that can facilitate the temporary boding of theactuator 1151 to the wall of the sequestration portion 1134.

In some embodiments, the sequestration portion 1134 can include one ormore openings or vents configured to allow a flow of gas and/or fluid tobe vented from the sequestration portion 1134. For example, asillustrated in FIG. 26, the sequestration portion 1134 can include anopening 1159 disposed in or in fluid communication with the secondportion of the sequestration portion 1134. The opening 1159 can serve tovent the contents disposed within the sequestration portion 1134, forexample, any volume of air or gaseous contents disposed within thesecond volume of the sequestration portion 1134 that is not fluidicallyconnected to the junction 1117, prior to use. As such, the opening 1159can allow for a venting of at least the second volume of thesequestration portion 1134 as the actuator 1151 is transitioned from thefirst state to the second state.

In some embodiments, the venting through the opening 1159 can be similarto the venting described above with reference to the devices 100, 200,300, 400, 500, 600, 700, 800, 900 and/or 1000. In the example shown inFIG. 26, however, the sequestration portion 1134 does not include a ventmaterial or the like disposed within the opening 1159 (as describedabove with reference to the other devices) because the arrangement ofthe actuator 1151 is such that the second volume of the sequestrationportion 1134 is fluidically isolated from the first volume of thesequestration portion 1134. As such, the second volume of thesequestration portion 1134 does not receive a volume of bodily fluidthat a vent material would otherwise prevent from exiting the opening1159. Although not shown, in other embodiments, the sequestrationportion 1134 can include a vent material, a selectively permeablemembrane, a flow controller, a one-way valve, etc. disposed withinand/or about the opening 1159 to, for example, limit and/orsubstantially prevent contaminants within the ambient environment fromentering into the second volume of the sequestration portion 1134.

While not shown in FIG. 26, in some embodiments, the sequestrationportion 1134 can also define an opening or vent that is in fluidcommunication with, for example, the first volume of the sequestrationportion 1134. In some such embodiments, the vent material can besubstantially similar to the vent materials described herein and can beconfigured to vent the first volume of the sequestration portion 1134.As described above with reference to previous embodiments, the ventingof the first volume of the sequestration portion 1134 can result in apressure differential between the first volume of the sequestrationportion 1134 and, for example, the junction 1117 that can result in adesired and/or predetermined flow of bodily fluid into the first volumeof the sequestration portion 1134. For example, in some instances,venting can allow for displacement of a volume of air or gas thatotherwise may resist the flow of bodily fluid. Thus, by venting thefirst volume of the sequestration portion 1134 and sealing and/orotherwise not venting a portion of the fluid flow path 1133 leading tothe outlet 1136, an initial flow from the inlet 1132 can flow though thejunction 1117 and into the first volume of the sequestration portion1134.

As described with reference to previous embodiments, the vent materialcan be transitioned from a first or selectively permeable state to asecond or substantially impermeable state in response to being saturatedand/or wetted by the initial flow of bodily fluid into the first volumeof the sequestration portion 1134. In some embodiments, the controldevice 100 can be configured such that a volume of bodily fluidsufficient to transition the vent material to the substantiallyimpermeable state also can be sufficient to dissolve the bondingmaterial 1155. In some embodiments, the vent or the like can be formedin a wall or surface of the sequestration portion 1134. In otherembodiments, the vent or the like can be formed in, for example, aportion of the actuator 1151 such that air or gas in the first volume ofthe sequestration portion 1134 is displaced and/or vented into thesecond volume of the sequestration portion 1134, which in turn, isvented to the ambient environment via the opening 1159.

As described in detail above, the device 1100 shown in FIG. 26 can beused to direct or divert a first or initial volume of bodily fluid suchthat subsequently procured bodily fluid samples have reducedcontamination from microbes such as, for example, dermally residingmicrobes and/or the like. For example, once a user such as a doctor,physician, nurse, phlebotomist, technician, etc. establishes, fluidcommunication between the device 1100 and the source of bodily fluid(e.g., as described in detail above with reference to previousembodiments), bodily fluid can flow from the bodily fluid source (e.g.,the vein of the patient or other suitable bodily fluid source) and intothe control device 1100. In some embodiments, the control device 1100can be in and/or can be placed in a first or initial state in which aninitial portion or volume of bodily fluid can flow through the inlet1132, a portion the fluid flow path 1133 and the junction 1117, and intothe sequestration portion 1134.

In some instances, the control device 1100 can remain in the first statewith the actuator 1151 in the initial state until a predetermined and/ordesired flow or volume of bodily fluid is transferred into the firstvolume of the sequestration portion 1134 that is in fluid communicationwith the junction 1117, which in turn, places at least a portion of thebodily fluid in contact with the dissolvable bonding substance 1155.Moreover, the predetermined and/or desired flow or volume of bodilyfluid can be associated with and/or at least partially based on anamount or volume of bodily fluid sufficient to dissolve the dissolvablebonding substance 1155 that holds the actuator 1151 in the initialstate. Accordingly, the dissolvable bonding substance 1155 can bedissolved in response to contact with at least a portion of the bodilyfluid transferred into the first volume of the sequestration portion1134 , which in turn, removes or releases the bond between the actuator1151 and the one or more surface and/or walls of the sequestrationportion 1134. Thus, with the bond and/or force removed or released, aforce associated with the spring 1154 in tension can move the actuator1151 from the initial state or position toward a subsequent state orposition. Said in another way, once the dissolvable bonding substance1155 no longer holds the actuator 1151 in the initial state against theforce of the tension in the spring 1154, the spring 1154 retracts,compresses, and/or otherwise releases the tension (e.g., by convertingpotential energy to kinetic energy) to be placed in a resting state,which in turn, transitions and/or moves the actuator 1151 connected tothe spring 1154 to the second state and/or position.

The movement of the actuator 1151 within the sequestration portion 1134changes and/or redistributes the first volume and the second volume ofthe sequestration portion 1134. That is, for example, as illustrated inFIG. 26, the movement of the actuator 1151 increases the first volume ofthe sequestration portion 1134 and decreases the second volume of thesequestration portion 1134. Moreover, the increase in the first volumeis accompanied by and/or otherwise results in a reduction in pressure(e.g., a suction force) in the first volume of the sequestration portion1134. Thus, with the control device 1100 being in a configuration orstate in which the sequestration portion 1134 is in fluid communicationwith the inlet 1132 (e.g., via the junction 1117 and at least a portionof the flow path 1133), the reduction in pressure can draw and/or canaid in drawing or urging flow of the initial volume of bodily fluid intothe first volume of the sequestration portion 1134.

In some embodiments, the amount and/or the rate of a volume of bodilyfluid drawn into the sequestration portion 1134 can be at leastpartially determined by the size of the first and second volumes of thesequestration portion 1134, one or more properties associated with theactuator 1151 (e.g., weight, mobility, inertial forces against itsmovement, friction forces, gravity, etc.), the rate of dissolution ofthe dissolvable bonding substance 1155, one or more properties of thespring 1154 (e.g., size, material, length, elasticity, allowable tensionforces, spring rate, etc.), and/or the like. Concurrently, the movementof the actuator 1151 and the decrease in the second volume of thesequestration portion 1134 can result in the venting of the contents(e.g., air or gas) of the second volume of the sequestration portion1134, by expulsion or release of the contents through the opening 1159.

In some embodiments, a size and/or configuration of the opening 1159 canbe varied, for example, to control and/or modify one or morecharacteristics associated with the venting of the second volume of thesequestration portion 1134. For example, in some embodiments, theopening 1159 can have a relatively small diameter configured to limitflow through the opening 1159 and/or a material configured to limit flowcan be disposed in the opening 1159. In such embodiments, the limitingand/or restricting of flow (e.g., air or gas flow) through the opening1159 can reduce a rate at which the second volume of the sequestrationportion 1134 is vented, which in turn, can slow and/or modulate a rateat which the actuator 1151 is moved with the sequestration portion 1134.In such embodiments, controlling the rate at which the actuator 1151 ismoved within the sequestration chamber 1134 can, for example, modulateand/or control an amount of negative pressure within the first volume ofthe sequestration portion 1134. In some embodiments, following thetransitioning and/or movement of the actuator 1151, and the venting ofthe second volume of the sequestration portion 1134, the opening 1159can be sealed by the actuator 1151, preventing any leak or flow ofbodily fluid through the opening 1159.

After the initial volume of bodily fluid is transferred and/or divertedinto the sequestration portion 1134 and/or (any other suitable portionof the device 1100), the initial volume is sequestered, segregated,retained, contained, isolated, etc. in the sequestration portion 1134.For example, in some embodiments, transferring the initial portion orvolume of bodily fluid into the resulting first volume of thesequestration portion 1134 can place the sequestration portion 1134 in afilled configuration and, as such, the volume of bodily fluid containedin the first portion of the sequestration portion 1134 substantiallyprevents any subsequent volume of bodily fluid from being disposedtherein. Further, in some embodiments, filling or substantially fillingthe first volume of the sequestration portion 1134 can reduce and/or cansubstantially equalize a pressure differential generated between thesequestration portion 1134 and the junction 1117, for example, and/orportion of the flow path 1133 that is in fluid communication with theinlet 1132. The decrease in and/or the substantial equalization of thepressure differential can be such that the flow of any subsequent volumeof fluid into the sequestration portion 1134 is limited and/or stops orsubstantially stops. In other embodiments, the junction 1117 and/orportion of the sequestration portion 1134 can include a valve, aselectively permeable membrane, fluid activated (e.g., bodily fluidactivated) switch or seal, user activated switch or seal, and/or thelike that can limit and/or substantially prevent a flow of bodily fluidinto or out of the sequestration portion 1134. As described above,contaminants such as, for example, dermally residing microbes or thelike dislodged during the venipuncture event, can be entrained and/orincluded in the initial volume of the bodily fluid and thus, can also besequestered in the sequestration portion 1134 when the initial volume issequestered therein.

Following the initial volume being sequestered in the sequestrationportion 1134, the device 1100 can transition to and/or can otherwise bein the second state in which a subsequent volume(s) of bodily fluid canflow through at least a portion of the fluid flow path 1133 from theinlet 1132, through the junction 1117, and to the outlet 1136. Asdescribed above, the outlet 1136 can be coupled to and/or placed influid communication with any suitable fluid collection device such as,for example, a sample reservoir, a syringe, and/or the like. In theembodiment shown in FIG. 26, the control device 1100 is configured toautomatically transition (e.g., without user intervention) from thefirst state to the second state once the initial volume of bodily fluidis sequestered in the final volume of the first portion of thesequestration portion 1134. Thus, as a subsequent flow and/or volume ofbodily fluid enters the fluid flow path 1133, the control device 1100directs and/or diverts the flow through the inlet 1132, a portion of thefluid flow path 1133, the junction 1117, and the outlet 1136. Asdescribed in detail above, the outlet 1136 is in fluid communicationwith one or more fluid collection device such that the subsequentvolume(s) of the bodily fluid can flow through the control device 1100and into the fluid collection device (not illustrated). Thus, asdescribed above, sequestering the initial volume of bodily fluid in thesequestration portion 1134 prior to collecting or procuring one or moresample volumes of bodily fluid reduces and/or substantially eliminatesan amount of contaminants in the one or more sample volumes.

Although the sequestration portion 1134 is described as including thespring 1154 configured to transition and/or move the actuator 1151, inother embodiments, the sequestration portion 1134 can include anysuitable energy storage member and/or any other device or mechanismconfigured to move the actuator 1151. For example, in some embodiments,the second volume of the sequestration portion 1134 can be evacuated,and a negative pressure therein can move the actuator 1151 when the oneor more components is/are removed, released, dissolved, transitioned,and/or deactivated. In other embodiments, the sequestration portion 1134can include a spring or other energy storage member that is loaded incompression and configured to move the actuator 1151. In some suchembodiments, the spring and/or energy storage member can be, forexample, disposed in the first volume of the sequestration portion 1134and/or the second volume of the sequestration portion 1134.

By way of example, FIG. 27 illustrates a fluid control device 1200according to another embodiment. The fluid control device 1200 (alsoreferred to herein as “control device” or “device”) can be any suitabledevice or set of devices configured to (1) receive a flow of bodilyfluid, (2) store and sequester a first volume or initial volume of thebodily fluid, and (3) direct, divert, and/or otherwise facilitate asubsequent flow of the bodily fluid to a fluid collection device (notillustrated). As described with respect to previous devices (e.g.,devices 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, and/or 1100)the control device 1200 can have any suitable size and/or shape. Forexample, in the embodiment shown in FIG. 27, the control device 1200includes an inlet 1232 (or inlet portion), an outlet 1236 (or outletportion), and a junction 1217, and includes and/or defines one or morefluid flow paths 1233 and a sequestration and/or diversion portion 1234(also referred to herein as “sequestration portion”). The inlet 1232 isconfigured to be placed in fluid communication with a bodily fluidsource (either directly or indirectly), as described in detail above.The outlet 1236 is configured to be coupled to a fluid collection device(not shown), as described in detail above. Accordingly, the inlet 1232and outlet 1236 are not described in further detail herein.

The device 1200 illustrated in FIG. 27 includes a first channel 1218 andsecond channel 1258 forming one or more junctions with or along aportion of the device 1200. For example, the first channel 1218 is influid communication with a first volume of the sequestration portion1234 and is configured to place the sequestration portion 1234 inselective fluid communication with the junction 1217. The second channel1258 is in fluid communication with a second volume of the sequestrationportion 1234 and is configured to selectively place the second volume ofthe sequestration portion 1234 in fluid communication with a portion ofthe flow path 1233. In some embodiments, the device 1200 and/or one ormore portions thereof can include one or more valves or seals toselectively control a flow of fluid in one or more directions. Forexample, in the example illustrated in FIG. 27, the device 1200 includesa valve 1257 disposed between and/or otherwise configured to control aflow of fluid between a portion of the junction 1217 and the firstchannel 1218. In some embodiments, the valve 1257 is configured topermit a flow of fluid from the junction 1217 and limit and/orsubstantially prevent a flow of fluid out of the first channel 1218. Thevalve 1257 can be any suitable valve such as, for example, a duckbillvalve, a butterfly valve, a one-way check valve, etc. and can be madefrom any suitable material, with any size, shape, and/or otherattributes, and configured with any suitable property. For example, thevalve 1257 can be designed to have specific cracking pressure or thelike (i.e., an amount of force or pressure needed to open the valve). Inother embodiments, the device 1200 can include any other suitable flowcontrol mechanism disposed between the junction 1217 and the firstchannel 1218 (e.g., other than a valve).

In some embodiments, the sequestration portion 1234 can be configured toinclude one or more flow controllers configured to selectively control aflow of fluid into and/or out of the sequestration portion 1234. Forexample, in some embodiments, the one or more flow controllers caninclude, for example, actuators, plungers, pistons, seals, vents,selectively permeable materials, and/or the like that are disposed inthe sequestration portion 1234 and configured to transition between oneor more states, configurations, positions, and/or the like. For example,the sequestration portion 1234 illustrated in FIG. 27 includes twoactuators or plungers 1251 and 1253 (e.g., flow controllers), connectedto each other through a connecting component 1252. The actuators 1251and 1253 (or plungers) are in contact with an inner surface of thesequestration portion 1234 such that a substantially fluid tight seal isformed between the actuators 1251 and 1253 and a portion of the innersurface. As shown in FIG. 27, the arrangement of the actuators 1251 and1253 within the sequestration portion 1234 separates and/or otherwisedefines three volumes of the sequestration portion 1234. The firstvolume of the sequestration portion 1234 is in fluid communication withthe first channel 1218 and a portion of the sequestration portion 1234defined between the valve 1257 and the first actuator 1251. The secondvolume of the sequestration portion 1234 is defined between the firstactuator 1251 and the second actuator 1253 and is in fluid communicationwith the second channel 1258. The third volume of the sequestrationportion 1234 is defined on a side of the second actuator 1253 oppositethe second volume of the sequestration portion 1234. The sequestrationportion 1234 also includes one (or more) seal(s) 1260 that is disposedaround the connecting component 1252. The seal 1260 is in contact withthe connecting component 1252 and the inner surfaces and/or walls of thesequestration portion 1234 and is configured to form a substantiallyfluid tight seal therebetween.

The sequestration portion 1234 also includes and/or defines one or moreopenings or vents configured to release or selectively permit release ofcontents disposed within the sequestration portion 1234. For example, asillustrated in FIG. 27, the sequestration portion 1234 defines anopening 1259 defined by and/or in fluid communication with the thirdvolume of the sequestration portion 1234. The opening 1259 can beconfigured to permit the expulsion of any air or gas disposed in thethird volume of the sequestration portion 1234, as described above withreference to the opening 1159 defined by the sequestration portion 1134(see e.g., FIG. 26). The sequestration portion 1234 can also includeand/or define an opening 1235 defined by and/or in fluid communicationwith the first volume of the sequestration portion 1234. As shown inFIG. 27, a vent material 1242 can be disposed within and/or about theopening 1235 and can be configured to selectively permit the release ofair or other gaseous contents within the first volume of thesequestration portion 1234 without permitting the release of a liquid(e.g., bodily fluid) from the first volume of the sequestration portion1234, as described above with reference to the vent material 242, 542,742, 842, 942, and/or 1042.

In some embodiments, the sequestration portion 1234 can include one ormore components, substances, compounds, chemicals, etc. that uponcontact with a volume of fluid (e.g., bodily fluid) can alter theirproperties and/or otherwise can react with the volume of fluid toproduce, for example, an actuation force or the like. For example, asshown in FIG. 27, the first volume of the sequestration portion 1234 caninclude one or more chemical substances 1256 that are configured toreact upon contact with a fluid (e.g., a bodily fluid) in a chemicalreaction that can produce and/or result in gaseous products. Thechemical substances 1256 can be any suitable substance(s). In someembodiments, the chemical substances 1256 can be dried or lyophilizedchemicals that can be reconstituted in response to being wetted.Moreover, the chemical substances 1256 can be such that upon wetting,one or more gaseous products are produced, which can expand within thefirst volume of the sequestration portion 1234 and can exert a force onthe first actuator 1251 that has a sufficient magnitude to move thefirst actuator 1251 within the sequestration portion 1234. The chemicalsubstances 1256 can be selected based at least in part on a size andconfiguration of the first volume of the sequestration portion 1234and/or the size and configuration of the first actuator 1251 such thatthe expansion of the gaseous reconstituted chemical exerts a desiredamount of force of the first actuator 1251 (e.g., an activation oractuation force). Moreover, the arrangement of the chemical substances1256, the actuators 1251 and 1253, and/or the vent material 1242 can beselected and/or configured to produce a desired amount of negativepressure within at least the first volume of the sequestration portion1234 that can be operable to draw bodily fluid into the sequestrationportion 1234, as described in further detail herein.

As described in detail above, the device 1200 shown in FIG. 27 can beused to transfer and/or divert a first or initial volume of bodily fluidsuch that subsequently procured bodily fluid samples have reducedcontamination from microbes such as, for example, dermally residingmicrobes and/or the like. For example, once a user such as a doctor,physician, nurse, phlebotomist, technician, etc. establishes fluidcommunication between the control device 1200 and the source of bodilyfluid (either directly or via an inlet device such as those describedabove), bodily fluid can flow from the bodily fluid source (e.g., thevein of the patient or any other suitable bodily fluid source) and intothe control device 1200. In some embodiments, the control device 1200can be in and/or can be placed in a first or initial state in which aninitial portion or volume of bodily fluid can flow through the inlet1232, at least a portion the fluid flow path 1233, at least a portion ofthe junction 1217, and the valve 1257, and into the sequestrationportion 1234 (and/or the first volume of the sequestration portion1234).

For example, in some instances, the control device 1200 can remain inthe first state with the actuators 1251 and 1253 in the initial stateuntil a predetermined and/or a first portion of bodily fluid istransferred through the valve 1257 and into the first volume of thesequestration portion 1234. The first portion of bodily fluid can beassociated with and/or at least partially based on an amount or volumeof bodily fluid that can pass the valve 1257, that is, a volumesufficient to generate a cracking force or pressure sufficient to openthe valve 1257. In some embodiments, the first portion of bodily fluidcan be an amount of bodily fluid that is transferred through the valve1257 in response to a positive pressure differential between the bodilyfluid source and, for example, the first volume of the sequestrationportion 1234. In some instances, the first portion of bodily fluid canbe a relatively small volume. In some instances, the venting of thefirst volume of the sequestration portion 1234 (e.g., through the ventmaterial 1242 and the opening 1235) can result in a desired and/orpredetermined flow of the first portion of the bodily fluid into thefirst volume of the sequestration portion 1234 rather than toward theoutlet 1236. That is to say, the venting of the first volume of thesequestration portion 1234 can draw the first portion of the flow ofbodily fluid through the valve 1257 and into the sequestration portion1234.

After the first portion of bodily fluid is transferred and/or divertedthrough the valve 1257 and into the first volume of the sequestrationportion 1234, the dried chemical substances 1256 can reconstitute, uponbeing wetted, resulting in a chemical reaction that produces one or moregaseous products, which in turn, expand within the first volume of thesequestration portion 1234. The expansion of the gas in the first volumeof the sequestration portion 1234 can increase a pressure therein thatcan be sufficient to close the valve 1257 (e.g., the one-way valve) andto exert a force on the first actuator 1251 to move the first actuator1251 within the sequestration portion 1234. Furthermore, the firstportion of the bodily fluid and/or a mixture of the chemical substances1256 and the first portion of the bodily fluid can contact, wet, and/orsaturate the vent material 1242 to transition the vent material 1242from its first or selectively permeable state to its second orsubstantially impermeable state. As such, the first volume of thesequestration portion 1234 can be substantially sealed as the chemicalsubstances 1256 expand, which in turn, increases a pressure within thefirst volume of the sequestration portion 1234 operable to move thefirst actuator 1251 from its first state and/or position toward itssecond state and/or position.

With the first actuator 1251 being connected to the second actuator 1253via the connecting component 1252 (e.g., a substantially rigidcomponent), the movement of the first actuator 1251 results in a similarmovement of the second actuator 1253. In some embodiments, the opening1259 in fluid communication with the third volume of the sequestrationportion 1234 can allow the third volume of the sequestration portion1234 to be vented as the second actuator 1253 is moved within thesequestration portion 1234, thereby preventing a buildup of pressurewithin the third volume of the sequestration portion 1234 that mightotherwise resist the movement of the actuators 1251 and 1253 (e.g., asdescribed above with reference to the control device 1100).

The arrangement of the seal 1260 is such that the seal 1260 is not movedduring at least an initial amount of movement of the actuators 1251 and1253. For example, as shown in FIG. 27, the seal 1260 can be disposed ona first side of the second channel 1258 and can be spaced apart from thefirst actuator 1251 when the device 1200 (or actuators 1251 and 1253) isin the initial state. As the gas expands, the actuators 1251 and 1253can move a predefined amount prior to the first actuator 1251 beingplaced in contact with the seal 1260. Thus, at least a portion of themovement of the actuators 1251 and 1253 is relative to the seal 1260(e.g., the seal 1260 does not move). Once the first actuator 1251contacts the seal 1260, however, the actuators 1251 and 1253 and theseal 1260 can move together in response to the force exerted by theexpanding gas in the first volume of the sequestration portion 1234.Although not shown in FIG. 27, in some embodiments, the sequestrationportion 1234 can include a vent in fluid communication with a volume ofthe sequestration portion 1234 defined between the first actuator 1251and the seal 1260. As such, when the first actuator 1251 is movedrelative to the seal 1260, air or gas disposed therein that mayotherwise resist and/or substantially prevent the relative movement canbe vented.

As described above, the second volume of the sequestration portion 1234(e.g., defined between the seal 1260 and the second actuator 1253 is influid communication with the second channel 1258, which in turn, is influid communication with the flow path 1233 (see FIG. 27). As such, themovement of the second actuator 1253 relative to the seal 1260 increasesa volume of the second volume of the sequestration portion 1234, whichin turn, results in a negative pressure therein. The negative pressurecan result in a negative pressure differential that is operable to drawbodily fluid through the inlet 1232, through at portion of the junction1217, through a portion of the flow path 1233, through the secondchannel 1258, and into the second volume of the sequestration portion1234. Thus, as the actuators 1251 and 1253 are moved (with or withoutthe seal 1260), an initial volume of bodily fluid can be drawn into thesecond volume of the sequestration portion 1234. Moreover, once thefirst actuator 1251 is placed in contact with the seal 1260, the seal1260 can be moved to a second side of the second channel 1258 oppositethe first side (described above). As such, when the actuators 1251 and1253 and the seal 1260 have completed the movement within thesequestration portion 1234, an initial volume of bodily fluid can bedrawn into the second volume of the sequestration portion 1234 andsequestered between the second actuator 1253 and the seal 1260. In otherwords, the seal 1260 can sequester the initial volume of bodily fluidfrom, for example, the second channel 1258, which in turn, sequestersthe initial volume of bodily fluid from the flow path 1233.

Following the initial volume being sequestered in the second volume ofthe sequestration portion 1234, the device 1200 can transition to and/orcan otherwise be in the second state in which a subsequent volume(s) ofbodily fluid can flow from the inlet 1232, through the junction 1217,the flow path 1233, and the outlet 1236, and into a fluid collectiondevice (not shown) coupled to the outlet 1236. In the embodiment shownin FIG. 27, the control device 1200 is configured to automaticallytransition (e.g., without user intervention) from the first state to thesecond state once the initial volume of bodily fluid is sequestered inthe second volume of the sequestration portion 1234. Thus, as asubsequent flow and/or volume of bodily fluid enters the fluid flow path1233, the control device 1200 directs and/or diverts the flow toward theoutlet 1236. As described in detail above, subsequent volume(s) ofbodily fluid can then flow through the control device 1200 and into thefluid collection device (not illustrated). In some embodiments, the flowpath 1233 can include one or more additional valves or flow controllersthat can be configured to selectively control bodily fluid flow from theinlet 1232 toward the outlet 1236. Moreover, a negative pressureproduced by a fluid collection device that is operable to draw bodilyfluid into the fluid collection device can also be operable to ensurethe valve 1257 remains in a closed or sealed state. Thus, as describedabove, sequestering the initial volume of bodily fluid in thesequestration portion 1234 prior to collecting or procuring one or moresample volumes of bodily fluid reduces and/or substantially eliminatesan amount of contaminants in the one or more sample volumes.

While the devices 1100 and 1200 are each described as includingjunctions configured, at least in part, to direct a flow of bodily fluidtoward sequestration portions and/or outlets, in other embodiments, adevice can be configured to direct fluid flow through the device withoutincluding a junction or the like. In such embodiments, an inlet can beselectively placed in fluid communication with a sequestration portionand/or an outlet via one or more flow controllers, actuators, select orconfigurable flow paths, and/or the like. For example, FIG. 28illustrates a fluid control device 1300 according to another embodiment.The fluid control device 1300 can be any suitable device or set ofdevices configured to (1) receive a flow of bodily fluid, (2) store andsequester a first volume or initial volume of the bodily fluid, and (3)direct, divert, and/or otherwise facilitate a subsequent flow of thebodily fluid to a fluid collection device (not illustrated). In someembodiments, the fluid control device 1300 (also referred to as “controldevice” or “device”) can be similar in at least form and/or function tothe control devices 1100 and/or 1200 described above with reference toFIG. 26 and FIG. 27, respectively. Accordingly, portions and/or aspectsof the control device 1300 are identified and/or briefly discussed belowfor context but are not described in further detail.

As shown in FIG. 28, the control device 1300 includes an inlet 1332 (orinlet portion), an outlet 1336 (or outlet portion), and includes and/ordefines one or more fluid flow paths 1333 and a sequestration and/ordiversion portion 1334 (also referred to herein as “sequestrationportion”). The inlet 1332 is configured to be placed in fluidcommunication with a bodily fluid source (either directly orindirectly), as described in detail above. The outlet 1336 is configuredto be coupled to a fluid collection device (not shown), as described indetail above. Accordingly, the inlet 1332 and outlet 1336 are notdescribed in further detail herein.

The sequestration portion 1334 can have any suitable shape and/or sizeto draw in a sufficient and/or desired volume of the bodily fluid (e.g.,a desired initial volume). As described above, in some embodiments, thesequestration portion 1334 can include one or more flow controllers suchas, for example, actuators, plungers, pistons, seals, vents, selectivelypermeable materials, valves, and/or the like that are disposed in thesequestration portion 1334 and configured to transition between one ormore states, configurations, positions, and/or the like. For example, asshown in FIG. 28, the sequestration portion 1334 includes two actuatorsand/or plungers 1351 and 1353 (e.g., flow controllers), connected toeach other through a connecting component 1352. In addition, thesequestration portion 1334 can include one (or more) seal(s) 1360 thatis/are disposed around the connecting component 1352. In someembodiments, the actuators and/or plungers 1351 and 1353, and theseal(s) 1360 can be substantially similar in form and/or function to theactuators and/or plungers 1251 and 1253, and the seals 1260,respectively, described above with reference to FIG. 27, and thus, arenot described in further detail herein.

The sequestration portion 1334 also includes and/or defines one or moreopenings or vents configured to vent or selectively permit the releaseof contents disposed within the sequestration portion 1334. For example,as illustrated in FIG. 28, the sequestration portion 1334 defines anopening 1359 in fluid communication with, for example, a first volume ofthe sequestration portion 1334 and can be configured to permit theexpulsion and/or venting of any air or gas disposed in the first volumeof the sequestration portion 1334 (e.g., in response to the actuators1351 and/or 1353), as described above with reference to the opening 1259defined by the sequestration portion 1234 (see e.g., FIG. 27). Thesequestration portion 1334 can also include and/or define an opening1335 defined by and/or in fluid communication with a second volume ofthe sequestration portion 1334. As shown in FIG. 29, a vent material1342 can be disposed within and/or about the opening 1335 and can beconfigured to selectively permit the release of air or other gaseouscontents within the first volume of the sequestration portion 1334without permitting the release of a liquid (e.g., bodily fluid) from thefirst volume of the sequestration portion 1334, as described above withreference to the vent material 242, 542, 742, 842, 942, and/or 1042.

In the embodiment shown in FIG. 28, the sequestration portion 1334 canalso include an energy storage member or the like configured totransition, for example, from a first state associated with a relativelyhigh potential energy to a second state associated with a relatively lowpotential energy. For example, the sequestration portion 1334 caninclude a spring 1354 connecting the actuator (or plunger) 1351 to awall or surface of the sequestration portion 1334. Moreover, thesequestration portion 1334 can include a dissolvable bonding substance1355 (e.g., glue, adhesive, fastener, epoxy, foam, and/or the like) thatat least temporarily bonds the first actuator 1351 to one or moresurfaces of the sequestration portion 1334 until it is dissolved, forexample, by contact with a flow of bodily fluid into the sequestrationportion 1334, which in turn, can allow for an activation and/or releaseof the spring 1354. As such, the arrangement and/or function of thefirst actuator 1351, the spring 1354, and the dissolvable bondingsubstance 1355 within the sequestration portion 1334 can besubstantially similar to the arrangement of the actuator 1151, thespring 1154, and the bonding substance 1155 described above withreference to FIG. 26.

While the spring 1154 is described above as having an initial or firststate in which the spring 1154 is placed in tension, the spring 1354shown in FIG. 28 can have an initial or first state in which the spring1354 is placed in compression prior to use. That is to say, prior touse, the dissolvable bonding substance 1355 can maintain the firstactuator 1351 in an initial or first position and, in turn, can maintainthe spring 1354 in the first or compressed state. An activation of thespring 1354 can result in the spring 1354 releasing an amount of storedenergy to move from the initial or compressed state to a subsequent oruncompressed state (e.g., having a lower potential energy). Accordingly,the spring 1354 can be operable to move the first actuator 1351 inresponse to bodily fluid contacting the dissolvable boding substance1355 whether the spring 1354 has an initial state in which the spring1354 is in compression (FIG. 28) or an initial state in which the spring1154 is in tension (FIG. 26).

As described in detail above with reference to the devices 1100 and1200, the device 1300 shown in FIG. 28 can be used to direct or divert afirst or initial volume of bodily fluid such that subsequently procuredbodily fluid samples have reduced contamination from microbes such as,for example, dermally residing microbes and/or the like. For example,once a user such as a doctor, physician, nurse, phlebotomist,technician, etc. establishes, fluid communication between the device1300 and the source of bodily fluid (e.g., as described in detail abovewith reference to previous embodiments), bodily fluid can flow from thebodily fluid source (e.g., the vein of the patient or other suitablebodily fluid source) and into the control device 1300. In someembodiments, the control device 1300 can be in and/or can be placed in afirst or initial state in which an initial portion or volume of bodilyfluid can flow through the inlet 1332, through a portion the fluid flowpath 1333, and into the sequestration portion 1334. Moreover, thearrangement of the control device 1300 can be such that when the device1300 is in the initial state, the fluid flow path 1333 places the inlet1332 in fluid communication with, for example, the second volume of thesequestration portion 1334 without the device 1300 including a junctionor the like (e.g., such as the junctions 1117 or 1217).

In some instances, the control device 1300 can remain in the first statewith the first actuator 1351 in the initial state until a predeterminedand/or desired flow or volume of bodily fluid is transferred into thesecond volume of the sequestration portion 1334 that is in fluidcommunication with the fluid flow path 1333. For example, as describedabove with reference to the device 1100, the desired volume of bodilyfluid can be a volume sufficient to dissolve the dissolvable bondingsubstance. Moreover, the second volume of the sequestration portion 1334can be vented through the vent material 1342 as the desired volume ofbodily fluid is transferred into the second volume of the sequestrationportion 1334, as described in detail above. Accordingly, the bodilyfluid can flow into the second volume of the sequestration portion 1334and into contact with the dissolvable bonding substance 1355, which inturn, is at least partially dissolved to an extent that a forceassociated with the spring 1354 in the initial state (e.g., incompression) overcomes a friction or adhesive force associated with thedissolvable bonding substance 1355. Thus, the spring 1355 can release anamount of stored and/or potential energy to transition to a second statein which the spring 1355 is uncompressed. Moreover, the transitioning ofthe spring 1355 from the first state to the second state moves the firstactuator 1351 from its initial state or position toward a subsequentstate or position. Said in another way, once the friction and/oradhesive force associated with the dissolvable bonding substance 1355 isovercome, the spring 1354 expands to be placed in a resting (e.g.,uncompressed) state, which in turn, transitions and/or moves the firstactuator 1351 connected to the spring 1354 to the second state and/orposition.

As described above with reference to the device 1200, with the firstactuator 1351 being connected to the second actuator 1353 via theconnecting component 1352 (e.g., a substantially rigid component), themovement of the first actuator 1351 results in a similar movement of thesecond actuator 1353, as indicated by the arrow DD in FIG. 28. In someembodiments, the opening 1359 in fluid communication with the firstvolume of the sequestration portion 1334 can allow the first volume ofthe sequestration portion 1334 to be vented as the second actuator 1353is moved within the sequestration portion 1334, thereby preventing abuildup of pressure within the first volume of the sequestration portion1334 that might otherwise resist the movement of the actuators 1351 and1353 (e.g., as described above with reference to the control device1100). In some embodiments, the arrangement of the seal 1360 is suchthat the seal 1360 is not moved during at least an initial amount ofmovement of the actuators 1351 and 1353. Accordingly, as described abovewith reference to the device 1200, the movement of the second actuator1353 relative to the seal 1360 increases a volume of the sequestrationportion 1334 defined therebetween, which in turn, produces a negativepressure operable to draw bodily fluid into the volume of thesequestration portion 1334.

After the actuators 1351 and 1353 are moved a desired distance relativeto the seal 1360, the seal 1360 can begin to move with the actuators1351 and 1353 (e.g., in response to a force exerted by the firstactuator 1351 or the like). As such, the actuators 1351 and 1353, andthe seal 1360 can move collectively within the sequestration portion1334 until the seal 1360 is moved to an opposite side of the inlet 1332.As such, when the actuators 1351 and 1353 and the seal 1360 havecompleted the movement within the sequestration portion 1334, an initialvolume of bodily fluid can be drawn into a volume of the sequestrationportion defined between the second actuator 1353 and the seal 1360 andcan be sequestered and/or isolated from the inlet 1332 (e.g., via theseal 1360).

Following the sequestration of the initial volume of bodily fluid, thedevice 1300 can transition to and/or can otherwise be in the secondstate in which the inlet 1332 is in fluid communication with the outlet1336. As described above, the outlet 1336 can be fluidically coupled toa fluid collection device (not shown) such that when the device is inthe second state, a subsequent volume of bodily fluid can be transferredthrough the inlet 1332, through the outlet 1336, and into the fluidcollection device. In the embodiment shown in FIG. 28, the controldevice 1300 can be configured to automatically transition (e.g., withoutuser intervention) from the first state to the second state once theinitial volume of bodily fluid is sequestered from the inlet 1332. Thus,as described above, sequestering the initial volume of bodily fluid inthe sequestration portion 1334 prior to collecting or procuring one ormore sample volumes of bodily fluid reduces and/or substantiallyeliminates an amount of contaminants in the one or more sample volumes.

While the sequestration portion 1334 is described above as including anenergy storage member such as the spring 1354 configured to move theactuators 1351 and 1353, and the seal(s) 1360 within the sequestrationportion 1334, in other embodiments, movement of one or more flowcontrollers, actuators, plungers, seals, etc. within a sequestrationportion can be actuated, activated, and/or initiated in any suitablemanner. For example, FIG. 29 illustrates a fluid control device 1400according to another embodiment. The fluid control device 1400 can beany suitable device or set of devices configured to (1) receive a flowof bodily fluid, (2) store and sequester a first volume or initialvolume of the bodily fluid, and (3) direct, divert, and/or otherwisefacilitate a subsequent flow of the bodily fluid to a fluid collectiondevice (not illustrated). In some embodiments, the fluid control device1400 (also referred to as “control device” or “device”) can be similarin at least form and/or function to the control device 1300 describedabove with reference to FIG. 28. Accordingly, portions and/or aspects ofthe control device 1400 are identified and/or briefly discussed belowfor context but are not described in further detail.

As shown in FIG. 29, the control device 1400 includes an inlet 1432 (orinlet portion), an outlet 1436 (or outlet portion), and includes and/ordefines one or more fluid flow paths 1433 and a sequestration and/ordiversion portion 1434 (also referred to herein as “sequestrationportion”). The inlet 1432 is configured to be placed in fluidcommunication with a bodily fluid source (either directly orindirectly), as described in detail above. The outlet 1436 is configuredto be coupled to a fluid collection device (not shown), as described indetail above. Accordingly, the inlet 1432 and outlet 1436 are notdescribed in further detail herein.

The sequestration portion 1434 can have any suitable shape and/or sizeto draw in a sufficient and/or desired volume of the bodily fluid (e.g.,a desired initial volume). As described above, in some embodiments, thesequestration portion 1434 can include one or more flow controllers suchas, for example, actuators, plungers, pistons, seals, vents, selectivelypermeable materials, valves, and/or the like that are disposed in thesequestration portion 1434 and configured to transition between one ormore states, configurations, positions, and/or the like. For example, asshown in FIG. 29, the sequestration portion 1434 includes two actuatorsand/or plungers 1451 and 1453 (e.g., flow controllers), connected toeach other through a connecting component 1452. In addition, thesequestration portion 1434 can include one (or more) seal(s) 1460 thatis/are disposed around the connecting component 1452. In someembodiments, the actuators and/or plungers 1451 and 1453, and theseal(s) 1460 can be substantially similar in form and/or function to theactuators and/or plungers 1351 and 1353, and the seals 1360,respectively, described above with reference to FIG. 28, and thus, arenot described in further detail herein.

The sequestration portion 1434 also includes and/or defines one or moreopenings or vents configured to vent or selectively permit the releaseof contents disposed within the sequestration portion 1434. For example,as illustrated in FIG. 29, the sequestration portion 1434 defines anopening 1459 in fluid communication with, for example, a first volume ofthe sequestration portion 1434 an opening 1435 in fluid communicationwith, for example, a second volume of the sequestration portion 1434. Asshown in FIG. 29, a vent material 1442 can be disposed within and/orabout the opening 1435. In some embodiments, the configuration,arrangement, and/or function of the openings 1459 and 1435, and the ventmaterial 1442 can be substantially to the configuration, arrangement,and/or function of the openings 1359 and 1335, and the vent material1342, described above with reference to FIG. 28 and thus, is notdescribed in further detail herein.

While the sequestration portion 1334 of the control device 1300 includedthe spring 1354 configured to move the actuators 1351 and 1351, and theseal(s) 1360, the sequestration portion 1434 shown in FIG. 29, can beconfigured to move the actuators 1451 and 1453, and seal(s) 1460 inresponse to a force associated with, for example, a chemical reaction,as described in detail above with reference to the control device 1200.For example, as shown in FIG. 29, the second volume of the sequestrationportion 1434 can include one or more chemical substances 1456 thatis/are configured to react upon contact with a fluid (e.g., a bodilyfluid) in a chemical reaction that can produce and/or result in gaseousproducts. In addition, the sequestration chamber 1434 can include avalve 1457 configured to control and/or selectively allow fluid flowinto or out of the second volume of the sequestration portion 1434, asdescribed in detail above with reference to the device 1200. Thechemical substances 1456 can be any suitable substance(s). In someembodiments, the chemical substances 1456 can be dried or lyophilizedchemicals that can be reconstituted in response to being wetted.Moreover, the chemical substances 1456 can be such that upon wetting,one or more gaseous products are produced, which can expand within thesecond volume of the sequestration portion 1434 and can exert a force onthe first actuator 1451 that has a sufficient magnitude to move thefirst actuator 1451 within the sequestration portion 1434, as describedin detail above with reference to the control device 1200.

As described in detail above, the device 1400 shown in FIG. 29 can beused to direct or divert a first or initial volume of bodily fluid suchthat subsequently procured bodily fluid samples have reducedcontamination from microbes such as, for example, dermally residingmicrobes and/or the like. For example, once a user such as a doctor,physician, nurse, phlebotomist, technician, etc. establishes, fluidcommunication between the device 1400 and the source of bodily fluid(e.g., as described in detail above with reference to previousembodiments), bodily fluid can flow from the bodily fluid source (e.g.,the vein of the patient or other suitable bodily fluid source) and intothe control device 1400. In some embodiments, the control device 1400can be in and/or can be placed in a first or initial state in which aninitial portion or volume of bodily fluid can flow through the inlet1432, at least a portion the fluid flow path 1433, and the valve 1457,and into the sequestration portion 1434 (and/or the first volume of thesequestration portion 1434).

For example, in some instances, the control device 1400 can remain inthe first state with the actuators 1451 and 1453 in the initial stateuntil a predetermined and/or a first portion of bodily fluid istransferred through the valve 1457 and into the second volume of thesequestration portion 1434. The first portion of bodily fluid can beassociated with and/or at least partially based on an amount or volumeof bodily fluid that can pass the valve 1457, that is, a volumesufficient to generate a cracking force or pressure sufficient to openthe valve 1457. In some embodiments, the first portion of bodily fluidcan be an amount of bodily fluid that is transferred through the valve1457 in response to a positive pressure differential between the bodilyfluid source and, for example, the second volume of the sequestrationportion 1434. In some instances, the first portion of bodily fluid canbe a relatively small volume. In some instances, the venting of thesecond volume of the sequestration portion 1434 can draw the firstportion of the flow of bodily fluid through the valve 1457 and into thesequestration portion 1434.

After the first portion of bodily fluid is transferred and/or divertedthrough the valve 1457 and into the second volume of the sequestrationportion 1434, the dried chemical substances 1456 can reconstitute, uponbeing wetted, resulting in a chemical reaction that produces one or moregaseous products, which in turn, expand within the second volume of thesequestration portion 1434. The expansion of the gas in the secondvolume of the sequestration portion 1434 can increase a pressure thereinthat can be sufficient to close the valve 1457 (e.g., the one-way valve)and to exert a force on the first actuator 1451 to move the firstactuator 1451 within the sequestration portion 1434. Furthermore, thefirst portion of the bodily fluid and/or a mixture of the chemicalsubstances 1456 and the first portion of the bodily fluid can contact,wet, and/or saturate the vent material 1442 to transition the ventmaterial 1442 from its first or selectively permeable state to itssecond or substantially impermeable state. As such, the second volume ofthe sequestration portion 1434 can be substantially sealed as thechemical substances 1456 expand, which in turn, increases a pressurewithin the second volume of the sequestration portion 1434 operable tomove the first actuator 1451 from its first state and/or position towardits second state and/or position, as described in detail above withreference to the control device 1200.

With the first actuator 1451 being connected to the second actuator 1453via the connecting component 1452 (e.g., a substantially rigidcomponent), the movement of the first actuator 1451 results in a similarmovement of the second actuator 1453, as indicated by the arrow EE inFIG. 29. In some embodiments, the opening 1459 in fluid communicationwith the first volume of the sequestration portion 1434 can allow thefirst volume of the sequestration portion 1434 to be vented as thesecond actuator 1453 is moved within the sequestration portion 1434,thereby preventing a buildup of pressure within the first volume of thesequestration portion 1434 that might otherwise resist the movement ofthe actuators 1451 and 1453 (e.g., as described above with reference tothe control device 1100). In some embodiments, the arrangement of theseal 1460 is such that the seal 1460 is not moved during at least aninitial amount of movement of the actuators 1451 and 1453. Accordingly,as described above with reference to the device 1200, the movement ofthe second actuator 1453 relative to the seal 1460 increases a volume ofthe sequestration portion 1434 defined therebetween, which in turn,produces a negative pressure operable to draw bodily fluid into thevolume of the sequestration portion 1434.

Following the sequestration of the initial volume of bodily fluid, thedevice 1400 can transition to and/or can otherwise be in the secondstate in which the inlet 1432 is in fluid communication with the outlet1436. As described above, the outlet 1436 can be fluidically coupled toa fluid collection device (not shown) such that when the device is inthe second state, a subsequent volume of bodily fluid can be transferredthrough the inlet 1432, through the outlet 1436, and into the fluidcollection device. In the embodiment shown in FIG. 29, the controldevice 1400 can be configured to automatically transition (e.g., withoutuser intervention) from the first state to the second state once theinitial volume of bodily fluid is sequestered from the inlet 1432. Thus,as described above, sequestering the initial volume of bodily fluid inthe sequestration portion 1434 prior to collecting or procuring one ormore sample volumes of bodily fluid reduces and/or substantiallyeliminates an amount of contaminants in the one or more sample volumes.

Referring now to FIG. 30, a flowchart is shown illustrating a method 10of using a fluid control device, such as those described herein, todivert an initial volume of bodily fluid to procure bodily fluid sampleswith reduced contamination, according to an embodiment. The fluidcontrol device (also referred to herein as “control device”) can besimilar to and/or substantially the same as any of the control devices100-1400 described herein.

The method 10 includes establishing fluid communication between a bodilyfluid source and an inlet of the control device, at 11. In someinstances, for example, the bodily fluid source can be a fluid sourcewithin a patient's body. More specifically, in some instances, thebodily fluid source can be a vein and/or vascular structure in thepatient's body. As described above, the control device can be configuredto couple to and/or include an inlet device such as, for example, anintravenous catheter, a butterfly needle, and/or the like. In otherembodiments, the inlet device can be any suitable coupler, port, etc.configured to fluidically couple to the bodily fluid source. As such,the inlet device can be manipulated to establish fluid communicationbetween the bodily fluid source and the fluid control device, asdescribed in detail above.

Having established fluid communication with the bodily fluid source, aninitial volume of bodily fluid is transferred from the bodily fluidsource to a sequestration chamber (e.g., sequestration and/or diversionportion or the like) defined by the control device when the controldevice is in a first state, at 12. In some embodiments, the controldevice or a portion thereof (e.g., the sequestration chamber, ajunction, an actuator, etc.) is in a first state and/or configurationprior to use. As such, establishing fluid communication with the bodilyfluid source automatically establishes fluid communication with thesequestration chamber. In other embodiments, the control device and/orone of the components of the control device is in an initial state thatallows partial transfer of bodily fluid into the sequestration chamberwhich then places the control device in the first state. In someembodiments, a control device can include one or more actuators thatplace the control device in the first state (e.g., as described above,for example, with reference to the sequestration and/or diversionportions 1134, 1234, 1334, and/or 1434).

As described in detail herein, the initial volume can be any suitablevolume of bodily fluid. For example, in some instances, the initialvolume can be as small as one drop of bodily fluid (or a relatively fewdrops of bodily fluid). In other instances, the initial volume can be,for example, up to about the volume of a lumen of a needle and/or avolume of a flow path between the patient and a sequestration portion ofthe device. In still other instances, the initial volume can be, forexample, up to about 0.25 mL, 0.5 mL, 1.0 mL, 2.0 mL, 5.0 mL, 10 mL, 20mL, 30 mL, 40 mL, 50 mL, or more. Moreover, as described in detail abovewith reference to specific embodiments, the initial volume can be atleast partially based on and/or can be associated with an amount ofbodily fluid that can be contained and/or sequestered in thesequestration chamber. In some instances the initial volume can be atleast partially based on and/or associated with a desired amount offluid to transition the control device from an initial state to thefirst state, using either passive (e.g., as described above withreference to the control devices 200, 300, and/or 400) or active methods(e.g., as described above with reference to the control devices 500and/or 600). For example, in some instances one or more actuators drivenby fluid volume or fluid contact can be activated with a pre-determinedstarting volume of fluid to place the control device in the first stateand an initial volume to further transition the control device from thefirst state to the second state, as described further below. In someinstances, the initial volume can be a volume that is sufficient toentrain and/or contain substantially all the undesired microbes that mayhave been dislodged and/or the like as the fluid communication was beingestablished between the bodily fluid source and the inlet device. Insome instances this step of transfer of an initial volume of bodilyfluid can be coupled with a concurrent venting of the sequestrationchamber of the control device through one or more openings, the openingssometimes disposed with mechanical valves or passively operatingmembranes, vent materials or the like. In some other instances howeverthe sequestration chamber can be pre-vented before the transfer on theinitial volume of fluid.

In response to the initial volume of bodily fluid being disposed in thesequestration chamber, the control device is transitioned (e.g.,automatically, passively, or in response to an actuation) from the firststate to the second state to sequester the initial volume of bodilyfluid in the sequestration chamber, at 13. In some embodiments, forexample, the initial volume of bodily fluid can fill the sequestrationchamber such that any additional volume of bodily fluid is preventedfrom entering and/or being contained in the sequestration chamber. Insuch embodiments, the filled sequestration chamber can form, forexample, a fluid lock or the like that prevents additional amounts ofbodily fluid from entering the sequestration chamber and/or thatprevents bodily fluid from exiting the sequestration chamber and/orportion. In some embodiments, the sequestration and/or diversion portioncan include any suitable flow controller such as those described herein.For example, in some embodiments, the sequestration chamber can includeand/or can house a hydrophilic material or the like (e.g., as describedabove with reference to the control devices 200, 400, 500, 600, 800,and/or 900) or one or more structures or components (e.g., as describedabove with reference to control devices 300 and/or 1000) that can absorband/or retain (e.g., sequester) the bodily fluid contained in thesequestration chamber. In some other embodiments, the sequestrationchamber can include actuators and/or seals (e.g., the actuators 1151 ofthe control device 1100 and/or the actuators or seals 1251, 1253, and/or1260 of the control device 1200) that are activated using any suitablemechanism to draw divert and/or sequester bodily fluid. For example,such embodiments can use any fluid-contact-activation such as theactivation described with reference to control devices 1100, 1200, 1300,and/or 1400, or can be user activated or activated on the basis of othervariables like time, pressure differential, gravity, or the like.

In some instances, two or more flow controllers or the like can be usedin combination. For example, in some embodiments, the diversion and/orsequestration of bodily fluid can be carried out using passivemechanisms (e.g., based on pressure differential and filling of thesequestration chamber, respectively). However, the diversion andsequestration of fluid can also result from one or more active methods,for example, one or more actuators operated without user intervention,such as one or more actuators activated by fluid contact that can drawand/or sequester bodily fluid (e.g., as described in the devices 1100,1200, 1300, and/or 1400). In some other embodiments, the actuators canalso be operated with user intervention, for example with an externalcontrol mechanism to activate or allow the movement of the actuators.One or more such user mediated mechanisms can be included in someembodiments to provide additional control function such as, for example,a supervisory or safety override function that may be used in certainsettings, for example, during training of personnel on the use of thecontrol devices. In other embodiments, the sequestration chamber canretain and/or sequester the initial volume of bodily fluid in anysuitable manner or combination of manners such as those describedherein.

With the control device being transitioned to the second state (e.g.,automatically, passively, and/or in response to user intervention), asubsequent volume of bodily fluid is transferred from the bodily fluidsource to a fluid collection device (e.g., any of those describedherein) in fluid communication with the control device, at 14. Asdescribed in detail above, the sequestering of the initial volume ofbodily fluid in the sequestration chamber likewise sequesters anycontaminants in the sequestration chamber. Accordingly, the subsequentvolume of bodily fluid transferred to the fluid collection device issubstantially free of contaminants.

FIG. 30 illustrates a method 20 of using a fluid control device, such asthose described herein, to obtain a bodily fluid sample with reducedcontamination according to an embodiment. The fluid control device (alsoreferred to herein as “control device”) can be similar to and/orsubstantially the same as any of the control devices 100-1400 describedherein.

The method 20 includes establishing fluid communication between a bodilyfluid source and an inlet of the control device, at 21. In someinstances, for example, the bodily fluid source can be a fluid sourcewithin a patient's body (e.g., the patient's vein). In other instances,the bodily fluid source can be any other suitable source of fluid suchas, for example, a source of bodily fluid that was previously obtainedand at least temporarily stored. As described above, in someembodiments, the control device can be configured to couple to and/orcan include an inlet device such as, for example, an intravenouscatheter, a butterfly needle, and/or the like. In other embodiments, theinlet device can be any suitable coupler, port, etc. configured tofluidically couple to the bodily fluid source. As such, the inlet devicecan be manipulated to establish fluid communication between the bodilyfluid source and the fluid control device, as described in detail above.

Having established fluid communication with the bodily fluid source, asequestration portion of the fluid control device is vented to produce afirst negative pressure differential between the sequestration portionof the fluid control device and the inlet of the fluid control device,at 22. In some embodiments, the sequestration portion can be ventedusing an active or passive mechanism such as those described herein. Forexample, in some embodiments, the sequestration portion can include avent material or the like that selectively vents a gas from thesequestration portion to result in the first negative pressuredifferential being produced between the sequestration portion and theinlet. In other embodiments, a control device can include one or moreactuators that place the control device in the first state (e.g., asdescribed above with reference to the sequestration portions 1134, 1234,1334, and/or 1434), that may also be operated to vent a sequestrationportion and/or produce the first negative pressure differential.

In response to the first negative pressure differential, an initialvolume of bodily fluid is received from the inlet and into thesequestration portion, at 23. In some embodiments, the flow controldevice can include a flow controller disposed in the sequestrationportion that is configured to be placed in contact with and/or otherwiseconfigured to interact with at least a portion of the initial volume ofthe bodily fluid. The method 20 includes transitioning the flowcontroller from a first state to a second state in response to the flowcontroller being placed in contact with the portion of the initialvolume of bodily fluid to produce a second negative pressuredifferential between the sequestration portion and the inlet such thatthe sequestration portion receives the initial volume of bodily fluidfrom the inlet, at 24.

As described in detail herein, the portion of the initial volume of thebodily fluid to come in contact with the flow controller can be anysuitable volume of bodily fluid. For example, in some instances, theportion of the initial volume can be as small as one drop of bodilyfluid (or a relatively few drops of bodily fluid). In other instances,the portion of the initial volume can be any suitable volume of bodilyfluid. Moreover, as described in detail above with reference to specificembodiments, the portion of the initial volume can be at least partiallybased on and/or can be associated with an amount of bodily fluid thatcan be necessary to transition the one or more flow controllers (e.g.,activate one or more actuators, as described with reference to fluidcontrol devices 1100, 1200, 1300, and/or 1400).

The initial volume of the bodily fluid can be any suitable volume ofbodily fluid, as described above with reference to the method 10.Moreover, as described in detail above with reference to specificembodiments, the initial volume can be at least partially based onand/or can be associated with an amount of bodily fluid that can becontained and/or sequestered in the sequestration chamber. In someinstances the initial volume can be at least partially based on and/orassociated with a desired amount of fluid to transition the controldevice from an initial state to the first state, using either passive oractive methods (such as those described herein). For example, in someinstances one or more actuators driven by fluid volume or fluid contactcan be activated with a pre-determined starting volume of fluid to placethe control device in the first state and an initial volume to furthertransition the control device from the first state to the second state,as described further below. In some instances, the initial volume can bea volume that is sufficient to entrain and/or contain substantially allthe undesired microbes that may have been dislodged and/or the like asthe fluid communication was being established between the bodily fluidsource and the inlet device.

The initial volume of bodily fluid is sequestered in the sequestrationportion when the flow controller is placed in the second state, at 25.For example, in response to the initial volume of bodily fluid beingdisposed in the sequestration portion, the control device can betransitioned (e.g., automatically, passively, or in response to anactuation) from the first state to the second state to sequester theinitial volume of bodily fluid in the sequestration portion. In someembodiments, for example, the initial volume of bodily fluid can fillthe sequestration chamber such that any additional volume of bodilyfluid is prevented from entering and/or being contained in thesequestration chamber. In such embodiments, the filled sequestrationchamber can form, for example, a fluid lock or the like that preventsadditional amounts of bodily fluid from entering the sequestrationchamber and/or that prevents bodily fluid from exiting the sequestrationchamber. In some embodiments, the sequestration portion can include ahydrophilic material or the like (e.g., as described above withreference to the control devices 200, 400, 500, 600, 800, and/or 900) orthe sequestration chamber can include one or more structures orcomponents (e.g., as described above with reference to control devices300 and/or 1000) that can absorb and/or retain (e.g., sequester) thebodily fluid contained in the sequestration chamber. In otherembodiments, the sequestration chamber can include a seal or the like(e.g., the seal 1260 described above with reference to control device1200) that is configured to sequester the initial volume of bodilyfluid.

In some instances, two or more flow controllers or the like can be usedin combination. For example, in some embodiments, the diversion and/orsequestration of the initial volume bodily fluid can be carried outusing passive mechanisms (e.g., based on pressure differential andfilling of the sequestration chamber, respectively). In otherembodiments, however, the diversion and sequestration of the initialvolume of bodily fluid can result from one or more active methods suchas, for example, one or more actuators operated without userintervention (e.g., fluid-activated actuators or the like as describedin the devices 1100, 1200, 1300, and/or 1400). In still otherembodiments, a flow controller can be operated and/or actuated via userintervention, for example, with an external control mechanism toactivate or allow the movement of the actuators. One or more such usermediated mechanisms can be included in some embodiments to provideadditional control function such as, for example, a supervisory orsafety override function that may be used in certain settings, forexample, during training of personnel on the use of the control devices.In other embodiments, the sequestration chamber can retain and/orsequester the initial volume of bodily fluid in any suitable manner orcombination of manners such as those described herein.

A subsequent volume of bodily fluid is transferred from the inlet to anoutlet of the control device in fluid communication with a fluidcollection device, at 26. As described in detail above, the sequesteringof the initial volume of bodily fluid in the sequestration portionsequesters any contaminants in the sequestration portion such that thesubsequent volume of bodily fluid transferred to the outlet issubstantially free of contaminants. Moreover, with the outlet in fluidcommunication with a fluid collection device, the subsequent volume ofbodily fluid can be collected and used, for example, in any suitablebodily fluid sample testing and/or the like (e.g., such as any of thosedescribed herein).

While various embodiments have been described above, it should beunderstood that they have been presented by way of example only, and notlimitation. Where schematics and/or embodiments described above indicatecertain components arranged in certain orientations or positions, thearrangement of components may be modified. While the embodiments havebeen particularly shown and described, it will be understood thatvarious changes in form and details may be made.

For example, while the inlet devices 110, 210, 310, 410, 510, 610, 710have been described above as including or coupling to a needle or thelike configured to puncture the skin of a patient to place the lumen ofthe needle in fluid communication with a vein in the patient, in otherembodiments, a fluid control device such as any of those describedherein can include any suitable inlet device. For example, in someembodiments, the inlet device can include a trocar or the like and acatheter. The trocar is configured to puncture the skin of a patient andthen configured to be withdrawn from the patient, leaving the catheterof the inlet device placed within the patient. In other embodiments, theinlet device need not puncture the skin of a patient. For example, insome embodiments, the inlet device can include a needle or catheter thatcan be placed in a dish, well, sample volume, container, reservoir, etc.In still other embodiments, the inlet device can be and/or can include acoupler or port configured to couple to an indwelling lumen-containingdevice, (e.g., a needle, tubing, or line), an indwelling intravenouscatheter, an indwelling central line (e.g., PICC, Hickman line,port-a-cath, etc.), and/or the like. In other embodiments, such acoupler or port can be configured to couple to any suitable bodily fluidsource (or port thereof) such as, for example, a syringe, a reservoir, acontainer, etc.

Accordingly, while the embodiments are described above as withdrawingand sequestering an initial volume of bodily fluid to sequestercontaminants such as, for example, dermally-residing microbes, in otherembodiments, the inlet device can be coupled to any suitable bodilyfluid source and can be configured to sequester an initial volume ofbodily fluid withdrawn from that bodily fluid source to sequestercontaminants that may be present within the source and/or any interfaceof the fluid collection pathway including the container or reservoircontaining the bodily fluid. For example, in some embodiments, a needleincluded in and/or coupled to an inlet device can be configured topuncture a port or surface of a reservoir to place the needle in fluidcommunication with an interior volume of the container or device. Insuch embodiments, the devices described herein can be used to sequesteran initial volume of bodily fluid from the bodily fluid source, which inturn, can sequester contaminants or the like that may have been presenton the interface, port, or surface that was punctured. Thus, the devicesand methods described herein can be used to procure bodily fluid sampleshaving reduced contamination from any suitable bodily fluid source.Moreover, while some such contaminants are described herein as beingdermally residing microbes, it should be understood that thecontaminants can be any contaminant that is, for example, exterior tothe bodily fluid source and/or otherwise that is, or that includes, anyconstituent component (e.g., microbe, virus, molecule, particle,element, etc.) that is otherwise foreign to the bodily fluid.

By way of another example, while the control devices 100-1400 aredescribed as having one or more flow controllers or the like configuredto facilitate the transfer of a bodily fluid into the device via passiveor active mechanisms or means of producing negative pressuredifferentials between two or more portions of the device, in otherembodiments, negative pressure differentials can be produced and/or canotherwise result from any suitable means. By way of example, in someembodiments, a control device can include a pre-charged sequestrationportion and/or chamber, a vented sequestration portion and/or chamber, amanually activated device configured to produce a negative pressure(e.g., within the sequestration portion), an energy source, and/or anyother suitable means of defining and/or forming a pressure differentialwithin a portion of the control device such as, for example, asequestration portion of the control device.

In other embodiments, an outlet of a control device can be coupled to asyringe, a pump, evacuated container, and/or any other suitable fluidcollection device that can produce a negative pressure differential. Forexample, in some embodiments, the device 400 be arranged and/orconfigured such that the fluid collection device coupled to the outlet436 provides a negative pressure or pressure differential that can beoperable to draw bodily fluid into the sequestration portion 434. Whilethe housing 430 of the device 400 is shown and described as being an“in-line” configuration, it should be understood that a fluid collectiondevice can be used to provide a negative pressure or pressuredifferential operable to draw bodily fluid into a sequestration portionin any of the embodiments described herein (e.g., in embodiments thatare not an “in-line” configuration). For example, in some embodiments, acontrol device can include parallel fluid flow paths or the like thatcan place an inlet in fluid communication with a sequestration portionand a fluid collection device in parallel. In some such embodiments, anegative pressure produced by the fluid collection device can beoperable to draw bodily fluid through the inlet of the control deviceand the control device can include any suitable means of directingand/or diverting an initial flow of the bodily fluid through thesequestration portion prior to directing and/or diverting a subsequentflow of bodily fluid to the fluid collection device.

Any of the fluid control devices described herein can be formed from anysuitable components that can be manufactured, sterilized, packaged,and/or sold independently as individual parts or components. In suchembodiments, a user can, for example, open one or more packagescontaining one or more components, can assemble the components to formthe fluid control device, and can use the fluid control device totransfer a bodily fluid sample with reduced contamination into a fluidcollection device (e.g., sample bottle, reservoir, syringe, etc.)connected to the fluid control device, as described above. In otherembodiments, any of the fluid control devices described herein can beformed from any suitable components that can be manufactured,sterilized, assembled, packaged, and/or sold as an assembly orintegrated device. In such embodiments, a user can, for example, open apackaging containing such an assembly or integrated device and can usethe device as described above without further assembly of components.

In some embodiments, any of the embodiments and/or components of theembodiments can be packaged and sold as a kit having any suitablecombination of components. For example, in some embodiments, a kit caninclude any suitable combination of a fluid control device, fluidcollection device, inlet device, and/or any other suitable component. Asanother example, a kit can include a fluid control device (such as thosedescribed herein), a needle or puncture member, an intravenous catheteror other lumen-containing device, one or more culture bottles (e.g., anaerobic and/or anaerobic culture bottle), one or more evacuatedcontainer (e.g., a Vacutainer® and/or the like), skin and/or otherantisepsis, a tourniquet, one or more bandages, pieces of gauze, cottonballs, etc., and/or any other suitable device and/or component. In someembodiments, such a kit can be disposed or assembled in a container in asterile environment and the container can be sealed in the sterileenvironment such that the inner volume of the container and thecomponents therein are substantial sterile prior to unsealing thecontainer. In other embodiments, any of the components can be sterilizedand packaged independently and later disposed or assembled in anon-sterile container. In other words, the individual sterilization andpackaging of the components can allow the container of the kit housingall of the components to be a non-sterile container or packaging.

Any of the control devices can be physically and/or fluidically coupledto a collection device (e.g., a sample reservoir, a syringe, a bloodculture bottle, a collection vial, a fluid transfer container, and/orany other suitable reservoir, collection device, and/or transfer device)by a user prior to or during use, as described in detail above. In otherembodiments, any of the control devices can be physically coupled to,attached to, mated to, and/or otherwise formed with (e.g., as anassembly or as an integral or monolithic construction) a fluidcollection device during a manufacturing process. This can be done priorto sterilization so the collection pathway(s) and connectioninterface(s) (e.g., where the control device couples to the fluidcollection device) maintain a closed-system, fluid control and/ormechanical diversion device within a sterile environment that is notsubject to touch-point contamination from external sources.

In some embodiments, the pre-assembly of the control device and thecollection device can be such that the user is forced first to divert,sequester, segregate, and/or isolate at least a portion of the initialbodily fluid volume or flow prior to transferring a sample volume to thepre-assembled fluid collection device (e.g., sample bottle, syringe,etc.). For example, the control device can include a flow controllersuch as a valve, actuator, selectively permeable membrane or member,seal, and/or the like that is configured to isolate an outlet from otherportions of the control device, thereby isolating the collection devicefrom such portions of the control device. Moreover, after transferringthe initial volume of bodily fluid, the flow controller and/or thecontrol device can be transitioned from a first state to a second state,which can result in sequestration of the initial volume of bodily fluidand the fluidic coupling of the outlet to additional portions of thecontrol device (e.g., an inlet). In some embodiments, pre-assembling thecontrol device and the collection device (e.g., during manufacturing)can, for example, force compliance with a sample procurement protocolthat calls for the sequestration of an initial amount of bodily fluidprior to collecting a sample volume of bodily fluid.

In some embodiments, the coupling, mating, and/or attachment of thefluid control device to the fluid collection device (e.g., duringmanufacturing) can be executed such that the control device can beremoved (physically decoupled, removed with a specific “key,” and/or anyother approach used to separate the control device from the fluidcollection device) after use to allow access to the fluid collectiondevice. After decoupling, the collection device (e.g., sample bottle orthe like) can be placed in an incubator and/or any other type ofanalytical machine, and accessed for analysis and/or otherwise furtherprocessed. In some embodiments, such decoupling may be blocked, limited,and/or substantially prevented prior to use and unblocked or allowedafter use. In other embodiments, the fluid control device and the fluidcollection device can be permanently coupled and/or monolithicallyformed (at least in part) to prevent such decoupling.

Any of the embodiments described herein can be used in conjunction withany suitable fluid transfer, fluid collection, and/or fluid storagedevice such as, for example, the fluid reservoirs described in the '420patent, the transfer devices described in the '510 publication, and/orthe transfer adapters described in the '352 publication. In someembodiments, any of the embodiments described herein can be used inconjunction with fluid transfer, fluid collection, and/or fluid storagedevices such as, for example, the devices described in U.S. Pat. No.8,535,241 entitled, “Fluid Diversion Mechanism for Bodily-FluidSampling,” filed Oct. 12, 2012; U.S. Pat.

Although various embodiments have been described as having particularfeatures, concepts, and/or combinations of components, other embodimentsare possible having any combination or sub-combination of any features,concepts, and/or components from any of the embodiments describedherein. For example, one or more methods of active user intervention canbe coupled with the above-described embodiments as an additional methodof control. For example, the diversion of fluid can be controlled by theabove-described automatic or passive (e.g., non-user mediated) methods,while additional control mechanisms for user-intervention (e.g., controlswitches, valves, ports) can be available to add and/or control variousparameters of fluid diversion such as volume, rate of diversion, and/orthe like.

The specific configurations of the various components can also bevaried. For example, the size and specific shape of the variouscomponents can be different from the embodiments shown, while stillproviding the functions as described herein. More specifically, the sizeand shape of the various components can be specifically selected for adesired rate and/or volume of bodily fluid flow into a fluid reservoir.Likewise, the size and/or shape of the various components can bespecifically selected for a desired or intended usage. For example, insome embodiments, devices such as those described herein can beconfigured for use with or on seemingly healthy adult patients. In suchembodiments, the device can include a sequestration portion (e.g.,reservoir, chamber, volume, lumen, etc.) that has a first volume (e.g.,about 0.5 ml to about 5.0 ml). In other embodiments, a device such asthose described herein can be configured for use with or on, forexample, very sick patients and/or pediatric patients. In suchembodiments, the device can include a sequestration portion that has asecond volume that is less than the first volume (e.g., less than about0.5 ml). Thus, size, shape, and/or arrangement of the embodiments and/orcomponents thereof can be adapted for a given use unless the contextexplicitly states otherwise.

Although not shown, any of the devices described herein can include anopening, port, coupler, septum, Luer-Lok, gasket, valve, threadedconnecter, standard fluidic interface, etc. (referred to for simplicityas a “port”) in fluid communication with the sequestration portion(e.g., chamber). In some such embodiments, the port can be configured tocouple to any suitable device, reservoir, pressure source, etc. Forexample, in some embodiments, the port can be configured to couple to areservoir, which in turn, can allow a greater volume of bodily fluid tobe diverted and/or transferred into the sequestration portion. In someembodiments, the port can be coupled to a negative pressure source suchas an evacuated container, a pump, a syringe, and/or the like to collecta portion of or the full volume of bodily fluid in the sequestrationportion and use that volume of bodily fluid (e.g., the pre-samplevolume) for additional clinical and/or in vitro diagnostic testingpurposes. In other embodiments, the port can be coupled to any suitablepressure source or infusion device configured to infuse the initialvolume of bodily fluid sequestered in the sequestration portion backinto the patient and/or bodily fluid source (e.g., in the case ofpediatric patients, very sick patients, patients having a low bloodvolume, and/or the like).

In some embodiments, the port can be configured to receive a probe,sampling tool, testing device, and/or the like that can be used toperform one or more tests (e.g., tests not sensitive to potentialcontamination) on the initial volume while the initial volume isdisposed or sequestered in the sequestration portion. In otherembodiments, the sequestration portion can be configured with theaddition of other diagnostic testing components integrated into theportion (e.g., a paper test) such that the initial bodily fluid is usedfor that test. In still other embodiments, the sequestration portion(e.g., chamber, channel, tube, bladder, container, volume, and/orreservoir) can be designed, sized, and configured to be removable andcompatible with testing equipment and/or specifically accessible forother types of bodily fluid tests commonly performed on patients withsuspected conditions. By way of example, a patient with suspected sepsiscommonly has blood samples collected for lactate testing, procalcitonintesting, and blood culture testing. All of the fluid control devicesdescribed herein can be configured such that the sequestration portioncan be removed (e.g., after receiving the initial volume of bodilyfluid) and the bodily fluid contained therein can be used for theseadditional testing purposes before or after the subsequent sample iscollected for microbial testing.

Although not shown, in some embodiments, a fluid control device caninclude one or more lumen, channels, flow paths, etc. configured toselectively allow for a “bypass” flow of bodily fluid, where an initialamount or volume of bodily fluid can flow from the inlet, through thelumen, channel, flow path, etc. to bypass the sequestration portion(e.g., reservoir, chamber, volume, etc.) and into the collection device.In some embodiments, the fluid control device can include an actuatorhaving, for example, at least three states—a first in which bodily fluidcan flow from the inlet to the sequestration portion, a second in whichbodily fluid can flow from the inlet to the outlet after the initialvolume is sequestered in the sequestration portion, and a third in whichbodily fluid can flow from the inlet, through the bypass flow path, andto the outlet. In other embodiments, the control device can include afirst actuator configured to transition the device between a first andsecond state, as described in detail above with reference to specificembodiments, and can include a second actuator configured to transitionthe device to a bypass configuration or the like. In still otherembodiments, the control device can include any suitable device,feature, component, mechanism, actuator, controller, etc. configured toselectively place the fluid control device in a bypass configuration orstate.

Where methods and/or events described above indicate certain eventsand/or procedures occurring in certain order, the ordering of certainevents and/or procedures may be modified and that such modifications arein accordance with the variations of the invention. Additionally,certain events and/or procedures may be performed concurrently in aparallel process when possible, as well as performed sequentially asdescribed above. Certain steps may be partially completed or may beomitted before proceeding to subsequent steps. For example, while thedevices are described herein as transitioning from a first state to asecond state in a discrete operation or the like, it should beunderstood that the devices described herein can be configured toautomatically and/or passively transition from the first state to thesecond state and that such a transitioning may occur over a period oftime. In other words, the transitioning from the first state to thesecond state may, in some instances, be relatively gradual such that asa last portion of the initial volume of bodily fluid is beingtransferred into the sequestration portion, the diverter, housing,and/or control device begins to transition from the first state to thesecond state. In some instances, the rate of change when transitioningfrom the first state to the second state can be selectively controlledto achieve one or more desired characteristics associated with thetransition. Moreover, in some such instances, the inflow of the lastportion of the initial volume can limit and/or substantially preventbodily fluid already disposed in the sequestration portion from escapingtherefrom. Accordingly, while the transitioning from the first state tothe second state may occur over a given amount of time, thesequestration portion can nonetheless sequester the volume of bodilyfluid disposed therein.

While the devices and methods have been described above as receiving andsequestering an initial volume of bodily fluid such that a subsequentvolume of bodily fluid substantially free of contaminants can becollected and used in any of the bodily fluid sample testing describedherein, in other embodiments, the devices and/or methods can be used,for example, in any other suitable procedure or the like. By way ofexample, in some embodiment, any of the devices described herein can beused to deliver a flow of fluid from a fluid source to the patient. Insuch embodiments, a fluid control device can be placed in fluidcommunication with a patient and can receive an initial flow or volumeof bodily fluid from the patient. As described in detail above, theinitial flow or volume of bodily fluid can be drawn and/or transferredinto a sequestration portion of the control device and sequesteredtherein. In some instances, receiving and sequestering the initial flowor volume of bodily fluid can, for example, sequester contaminantsand/or the like (e.g., contaminants dislodged during venipuncture and/orany other contaminants, microbes, etc.) within the initial volume. Inresponse to and/or after sequestering the initial volume of bodilyfluid, the fluid control device can be transitioned to a second state inwhich an outlet of the fluid control device is coupled to a fluidsource. Accordingly, a volume of the fluid can be transferred from thefluid source, through the fluid control device, and to the patient whilebypassing the initial volume of bodily fluid sequestered in thesequestration portion of the fluid control device. In other instances,any of the fluid control devices described herein can be used in anysuitable procedure and need not be limited to transferring fluid to orfrom a patient.
